Pattern-Based Contractility Screening, a Reference-Free Alternative to Traction Force Microscopy Methodology.

ACS Appl Mater Interfaces 2021 May 22;13(17):19726-19735. Epub 2021 Apr 22.

Department of Bioengineering, McGill University, Montreal H3A 0E9, Canada.

The sensing and generation of cellular forces are essential aspects of life. Traction force microscopy (TFM) has emerged as a standard broadly applicable methodology to measure cell contractility and its role in cell behavior. While TFM platforms have enabled diverse discoveries, their implementation remains limited in part due to various constraints, such as time-consuming substrate fabrication techniques, the need to detach cells to measure null force images, followed by complex imaging and analysis, and the unavailability of cells for postprocessing.

Chemical interaction of 4-META with enamel in resin-enamel bonds.

Dent Mater J 2021 Jan 30. Epub 2021 Jan 30.

Division of Biomaterials and Bioengineering, School of Dentistry, Health Sciences University of Hokkaido.

X-ray photoelectron spectroscopy (XPS) is used to analyze 4-META resin and enamel that are debonded at an adhesive interface. The XPS spectra showed two chemical states for Ca: one resulted from Ca of hydroxyapatite and the other, an unknown chemical state, suggested that Ca was chemically bonded with 4-META. We postulate that for a chemical reaction of 4-META and hydroxyapatite, the chemical structure of carboxyl groups will resemble that of calcium phthalate. Read More

Key Properties of a Bioactive Ag-SiO/TiO Coating on NiTi Shape Memory Alloy as Necessary at the Development of a New Class of Biomedical Materials.

Int J Mol Sci 2021 Jan 6;22(2). Epub 2021 Jan 6.

Refractory Materials Division in Gliwice, Łukasiewicz Research Network-Institute of Ceramics and Building Materials, Toszecka 99, 44-100 Gliwice, Poland.

Recent years have seen the dynamic development of methods for functionalizing the surface of implants using biomaterials that can mimic the physical and mechanical nature of native tissue, prevent the formation of bacterial biofilm, promote osteoconduction, and have the ability to sustain cell proliferation. One of the concepts for achieving this goal, which is presented in this work, is to functionalize the surface of NiTi shape memory alloy by an atypical glass-like nanocomposite that consists of SiO-TiO with silver nanoparticles. However, determining the potential medical uses of bio(nano)coating prepared in this way requires an analysis of its surface roughness, tribology, or wettability, especially in the context of the commonly used reference coat-forming hydroxyapatite (HAp).
