Composite nanostructures and adhesion analysis of natural plant hydrogels investigated by atomic force microscopy.

IEEE Trans Nanobioscience 2019 Apr 12. Epub 2019 Apr 12.

Hydrogels designed by biomimetism and bioinspiration have been considered as a promising biomaterial for biomedical applications due to their biocompatible characteristics. Though biomimetic or bioinspired hydrogels have been widely studied by biochemical analysis, so far the detailed organizations and properties of native natural hydrogels are still not fully understood. The advent of atomic force microscopy (AFM) provides a potent tool for probing the biological samples in their living states with nanometer spatial resolution, which offers new possibilities for addressing the biological and material issues at the nanoscale.

Designing bioinspired surfaces for water collection from fog.

Philos Trans A Math Phys Eng Sci 2019 Feb;377(2138):20180269

Nanoprobe Laboratory for Bio- & Nanotechnology and Biomimetics (NLBB), The Ohio State University , 201 W. 19th Avenue, Columbus, OH 43210-1142 , USA.

A systematic study is presented on various water collectors, bioinspired by desert beetles, desert grass and cacti. Three water collecting mechanisms including heterogeneous wettability, grooved surfaces, and Laplace pressure gradient, were investigated on flat, cylindrical, conical surfaces, and conical array. It is found that higher water repellency in flat surfaces results in higher water collection rate and inclination angle (with respect to the vertical axis) has little effect. Read More

Spatially variant microstructured adhesive with one-way friction.

J R Soc Interface 2019 Jan;16(150):20180705

2 Department of Mechanical Engineering, University of California , Santa Barbara, CA 93106 , USA.

Surface microstructures in nature enable diverse and intriguing properties, from the iridescence of butterfly wings to the hydrophobicity of lotus leaves to the controllable adhesion of gecko toes. Many artificial analogues exist; however, there is a key characteristic of the natural materials that is largely absent from the synthetic versions-spatial variation. Here we show that exploiting spatial variation in the design of one class of synthetic microstructure, gecko-inspired adhesives, enables one-way friction, an intriguing property of natural gecko adhesive.

ACS Nano 2019 Apr 4. Epub 2019 Apr 4.

Department of Biomaterials , Max Planck Institute of Colloids and Interfaces , Research Campus Golm, D-14424 Potsdam , Germany.

Natural materials provide an increasingly important role model for the development and processing of next-generation polymers. The velvet worm Euperipatoides rowelli hunts using a projectile, mechanoresponsive adhesive slime that rapidly and reversibly transitions into stiff glassy polymer fibers following shearing and drying. However, the molecular mechanism underlying this mechanoresponsive behavior is still unclear. Read More

Heart valve inspired and multi-stream aortic cannula: Novel designs for cardiopulmonary bypass improvement in neonates.

Artif Organs 2019 Mar 27. Epub 2019 Mar 27.

Department of Mechanical Engineering, Koç University, Sarıyer, Istanbul, Turkey.

In a typical open-heart surgery, the blood flow through the aortic cannula is a critical element of the cardiopulmonary bypass (CPB) procedure. Especially for the neonatal and pediatric CPB flow conditions, the need for small hydraulic diameter and large blood flow results confined turbulent jet flow regimes that exacerbate blood damage and platelet activation. Simultaneously, the confined jet wake leads to complex stagnation and recirculating flows that cause considerable thrombosis, blood and endothelial cell damage through the aorta. Read More

Ecosystem Function and Services of Aquatic Predators in the Anthropocene.

Trends Ecol Evol 2019 Apr 8;34(4):369-383. Epub 2019 Mar 8.

Fish Ecology and Conservation Physiology Laboratory, Carleton University, Ottawa, ON K1S 5B6, Canada. Electronic address: https://twitter.com/Cooke.

Arguments for the need to conserve aquatic predator (AP) populations often focus on the ecological and socioeconomic roles they play. Here, we summarize the diverse ecosystem functions and services connected to APs, including regulating food webs, cycling nutrients, engineering habitats, transmitting diseases/parasites, mediating ecological invasions, affecting climate, supporting fisheries, generating tourism, and providing bioinspiration. In some cases, human-driven declines and increases in AP populations have altered these ecosystem functions and services. Read More

Natural History Collections as Inspiration for Technology.

Bioessays 2019 Feb;41(2):e1700238

Dr. J. A. Watson, Dr. G. S. Watson, School of Science and Engineering, University of the Sunshine Coast, Fraser Coast, Hervey Bay, QL, 4655, Australia.

Living organisms are the ultimate survivalists, having evolved phenotypes with unprecedented adaptability, ingenuity, resourcefulness, and versatility compared to human technology. To harness these properties, functional descriptions and design principles from all sources of biodiversity information must be collated - including the hundreds of thousands of possible survival features manifest in natural history museum collections, which represent 12% of total global biodiversity. This requires a consortium of expert biologists from a range of disciplines to convert the observations, data, and hypotheses into the language of engineering. Read More

Soft Matter Technology at KIT: Chemical Perspective from Nanoarchitectures to Microstructures.

Adv Mater 2019 Feb 10:e1806334. Epub 2019 Feb 10.

Soft Matter Synthesis Laboratory, Institute for Biological Interfaces 3 (IBG 3), Karlsruhe Institute of Technology (KIT), Hermann-von-Helmholtz-Platz 1, 76344, Eggenstein-Leopoldshafen, Germany.

Bioinspiration has emerged as an important design principle in the rapidly growing field of materials science and especially its subarea, soft matter science. For example, biological cells form hierarchically organized tissues that not only are optimized and designed for durability, but also have to adapt to their external environment, undergo self-repair, and perform many highly complex functions. Being able to create artificial soft materials that mimic those highly complex functions will enable future materials applications. Read More

Bioinspired design and additive manufacturing of soft materials, machines, robots, and haptic interfaces.

Angew Chem Int Ed Engl 2019 Feb 1. Epub 2019 Feb 1.

Tsinghua University, CHINA.

Soft materials possess several distinctive characteristics like controllable deformation, infinite degrees of freedom, and self-assembly that make them promising candidates for building soft machines, robots, and haptic interfaces. In this article, we review recent advances in intrinsically soft materials, and soft-material-enabled robots, machines, and haptic interfaces, with emphasis on two specific topics-bioinspired design and additive manufacturing. Biology is an abundant source of inspiration that many materials and systems use to mimic the functions or mechanisms of biological tissues, agents, and behaviors. Read More

Adaptive structural reorientation: Developing extraordinary mechanical properties by constrained flexibility in natural materials.

Acta Biomater 2019 Mar 11;86:96-108. Epub 2019 Jan 11.

Department of Materials Science and Engineering, University of California Berkeley, Berkeley, CA 94720, USA. Electronic address:

Seeking strategies to enhance the overall combinations of mechanical properties is of great significance for engineering materials, but still remains a key challenge because many of these properties are often mutually exclusive. Here we reveal from the perspective of materials science and mechanics that adaptive structural reorientation during deformation, which is an operating mechanism in a wide variety of composite biological materials, functions more than being a form of passive response to allow for flexibility, but offers an effective means to simultaneously enhance rigidity, robustness, mechanical stability and damage tolerance. As such, the conflicts between different mechanical properties can be "defeated" in these composites merely by adjusting their structural orientation. Read More

Triple-Bioinspired Burying/Crosslinking Interfacial Coassembly Strategy for Layer-by-Layer Construction of Robust Functional Bioceramic Self-Coatings for Osteointegration Applications.

ACS Appl Mater Interfaces 2019 Jan 17;11(4):4447-4469. Epub 2019 Jan 17.

Department of Materials Science and Engineering, College of Engineering , Peking University , Beijing 100871 , China.

Coating bioceramics of inherent bioactivity onto biometallic implants is a straightforward yet promising solution to address poor osteointegration of the latter. One step further, it would be a nontrivial accomplishment to develop a mild, cheap, and universal route to firmly stabilizing, in principle, any ceramics onto any implant substrate, while imparting expectedly versatile biofunctional performances. Herein, we describe a triple-bioinspired burying/cross-linking interfacial coassembly strategy for enabling such ceramic coatings, which ingeniously fuses bioinspiration from sea rocks (burying assisted particle immobilization), marine mussels (universal adhesion and versatile chemical reactivity), and reef-building oysters (cross-linking rendered cohesion).

Looking deep into nature: A review of micro-computed tomography in biomimicry.

Acta Biomater 2019 Feb 10;85:27-40. Epub 2018 Dec 10.

Laboratory of Functional Morphology, Department of Biology, University of Antwerp, Universiteitsplein 1, 2610 Wilrijk, Belgium.

Albert Einstein once said "look deep into nature, and then you will understand everything better". Looking deep into nature has in the last few years become much more achievable through the use of high-resolution X-ray micro-computed tomography (microCT). The non-destructive nature of microCT, combined with three-dimensional visualization and analysis, allows for the most complete internal and external "view" of natural materials and structures at both macro- and micro-scale.

Hydration-induced nano- to micro-scale self-recovery of the tooth enamel of the giant panda.

Acta Biomater 2018 11 28;81:267-277. Epub 2018 Sep 28.

Department of Materials Science and Engineering, University of California Berkeley, Berkeley, CA 94720, USA. Electronic address:

The tooth enamel of vertebrates comprises a hyper-mineralized bioceramic, but is distinguished by an exceptional durability to resist impact and wear throughout the lifetime of organisms; however, enamels exhibit a low resistance to the initiation of large-scale cracks comparable to that of geological minerals based on fracture mechanics. Here we reveal that the tooth enamel, specifically from the giant panda, is capable of developing durability through counteracting the early stage of damage by partially recovering its innate geometry and structure at nano- to micro- length-scales autonomously. Such an attribute results essentially from the unique architecture of tooth enamel, specifically the vertical alignment of nano-scale mineral fibers and micro-scale prisms within a water-responsive organic-rich matrix, and can lead to a decrease in the dimension of indent damage in enamel introduced by indentation.

Simultaneous improvements of strength and toughness in topologically interlocked ceramics.

Proc Natl Acad Sci U S A 2018 09 23;115(37):9128-9133. Epub 2018 Aug 23.

Department of Mechanical Engineering, McGill University, Montreal, QC H3A 2K6, Canada

Topologically interlocked materials (TIMs) are an emerging class of architectured materials based on stiff building blocks of well-controlled geometries which can slide, rotate, or interlock collectively providing a wealth of tunable mechanisms, precise structural properties, and functionalities. TIMs are typically 10 times more impact resistant than their monolithic form, but this improvement usually comes at the expense of strength. Here we used 3D printing and replica casting to explore 15 designs of architectured ceramic panels based on platonic shapes and their truncated versions. Read More

Woods provide bioinspiration for engineering materials due to their superior mechanical performance. We demonstrate a novel strategy for large-scale fabrication of a family of bioinspired polymeric woods with similar polyphenol matrix materials, wood-like cellular microstructures, and outstanding comprehensive performance by a self-assembly and thermocuring process of traditional resins. In contrast to natural woods, polymeric woods demonstrate comparable mechanical properties (a compressive yield strength of up to 45 MPa), preferable corrosion resistance to acid with no decrease in mechanical properties, and much better thermal insulation (as low as ~21 mW m K) and fire retardancy.

Owls are a master to achieve silent flight in gliding and flapping flights under natural turbulent environments owing to their unique wing morphologies. While the leading-edge serrations are recently revealed, as a passive flow control micro-device, to play a crucial role in aerodynamic force production and sound suppression (Rao et al 2017 Bioinspiration Biomim. 12 1-13), the characteristics of wind-gust rejection associated with leading-edge serrations remain unclear.

O-, N-Atoms-Coordinated Mn Cofactors within a Graphene Framework as Bioinspired Oxygen Reduction Reaction Electrocatalysts.

Adv Mater 2018 Jul 28;30(28):e1801732. Epub 2018 May 28.

Hefei National Laboratory for Physical Science at Microscale, Department of Materials Science & Engineering and Collaborative Innovation Center of Suzhou Nano Science and Technology, University of Science and Technology of China, Hefei, 230026, P. R. China.

Manganese (Mn) is generally regarded as not being sufficiently active for the oxygen reduction reaction (ORR) compared to other transition metals such as Fe and Co. However, in biology, manganese-containing enzymes can catalyze oxygen-evolving reactions efficiently with a relative low onset potential. Here, atomically dispersed O and N atoms coordinated Mn active sites are incorporated within graphene frameworks to emulate both the structure and function of Mn cofactors in heme-copper oxidases superfamily.

This study investigates the aerodynamic efficiency of a bioinspired flapping wing rotor kinematics which combines an active vertical flapping motion and a passive horizontal rotation induced by aerodynamic thrust. The aerodynamic efficiencies for producing both vertical lift and horizontal thrust of the wing are obtained using a quasi-steady aerodynamic model and two-dimensional (2D) CFD analysis at Reynolds number of 2500. The calculated efficiency data show that both efficiencies (propulsive efficiency-, and efficiency for producing lift- ) of the wing are optimized at Strouhal number () between 0. Read More

Effect of microtrichia on the interlocking mechanism in the Asian ladybeetle, (Coleoptera: Coccinellidae).

Beilstein J Nanotechnol 2018 6;9:812-823. Epub 2018 Mar 6.

Key Laboratory of Bionic Engineering (Ministry of Education, China), Jilin University, Changchun, 130022, P.R. China.

The hindwings of beetles are folded under the elytra when they are at rest but are extended during flight, which can provide bioinspiration for the design of deployable micro air vehicles (MAVs). Beetle hindwings must be able to be both securely locked under the elytra and freely extended for flight, depending on the required action. To investigate the locking mechanism, this study used environmental scanning electron microscopy (ESEM) to examine the microstructures of the elytra, hindwings and abdomen of the Asian ladybeetle, (Pallas, 1773).

3D Printing of Materials with Tunable Failure via Bioinspired Mechanical Gradients.

Adv Mater 2018 May 16;30(19):e1705808. Epub 2018 Jan 16.

Complex Materials, Department of Materials, ETH Zürich, 8093, Zürich, Switzerland.

Mechanical gradients are useful to reduce strain mismatches in heterogeneous materials and thus prevent premature failure of devices in a wide range of applications. While complex graded designs are a hallmark of biological materials, gradients in manmade materials are often limited to 1D profiles due to the lack of adequate fabrication tools. Here, a multimaterial 3D-printing platform is developed to fabricate elastomer gradients spanning three orders of magnitude in elastic modulus and used to investigate the role of various bioinspired gradient designs on the local and global mechanical behavior of synthetic materials.

Bioinspired microneedle insertion for deep and precise skin penetration with low force: Why the application of mechanophysical stimuli should be considered.

J Mech Behav Biomed Mater 2018 02 7;78:480-490. Epub 2017 Dec 7.

Department of Mechanical Engineering, Inha University, Incheon 22212, Republic of Korea. Electronic address:

A mosquito is known to precisely and easily insert its proboscis to the human skin by pressing down a labium and vibrating a fascicle bundle. Its advanced skin-piercing mechanisms indicate that skin resistance to the insertion of needle-like objects can be changed by the application of mechanophysical stimuli. Here, we characterize the effect of the application of mechanophysical stimuli on skin resistance to microneedle insertion to find clues for inserting a microneedle in a deep and precise fashion with low force.

Functional Design of Highly Robust and Flexible Thin-Film Encapsulation Composed of Quasi-Perfect Sublayers for Transparent, Flexible Displays.

ACS Appl Mater Interfaces 2017 Dec 11;9(50):43983-43992. Epub 2017 Dec 11.

School of Electrical Engineering, KAIST , Daejeon 34141, Republic of Korea.

In this study, a structurally and materially designed thin-film encapsulation is proposed to guarantee the reliability of transparent, flexible displays by significantly improving their barrier properties, mechanical stability, and environmental reliability, all of which are essential for organic light-emitting diode (OLED) encapsulation. We fabricated a bioinspired, nacre-like ZnO/AlO/MgO laminate structure (ZAM) using atomic layer deposition for the microcrack toughening effect. The ZAM film was formed with intentional voids and defects through the formation of a quasi-perfect sublayer, rather than the simple fabrication of nanolaminate structures. Read More

Technical University of Munich Chair of Biogenic Polymers, Schulgasse 16, D-94315, Straubing, Germany.

Bioinspiration, biomorphy, biomimicry, biomimetics, bionics, and biotemplating are terms used to describe the fabrication of materials or, more generally, systems to solve technological problems by abstracting, emulating, using, or transferring structures from biological paradigms. Herein, a brief overview of how the different terminologies are being typically applied is provided. It is proposed that there is a rich field of research that can be expanded by utilizing various novel approaches for the guidance of living organisms for "bio-mediated" material structuring purposes.

The mechanics of hydrogel crawlers in confined environment.

J R Soc Interface 2017 07;14(132)

Mechanical Engineering, University of Colorado Boulder, 427 UCB, Boulder, CO, USA.

We present theoretical and experimental results regarding the development of temperature-sensitive hydrogel particles that can display self-motility in confined channels. Inspired by the motility of living organisms such as larva, the motion of the particle relies on the combination of two key mechanisms. The first, referred to as actuation, is enabled by the cyclic extension and retraction of the particle owing to oscillations of its temperature around the so-called lower critical solution temperature.

Department of Mechanical Science and Engineering, University of Illinois at Urbana-Champaign , Urbana, Illinois 61801, United States.

Evolutionary pressure has pushed many extant species to develop micro/nanostructures that can significantly affect wettability and enable functionalities such as droplet jumping, self-cleaning, antifogging, antimicrobial, and antireflectivity. In particular, significant effort is underway to understand the insect wing surface structure to establish rational design tools for the development of novel engineered materials. Most studies, however, have focused on superhydrophobic wings obtained from a single insect species, in particular, the Psaltoda claripennis cicada. Read More
