Immobilized aptamer on gold electrode senses trace amount of aflatoxin M1.

Appl Nanosci 2017 13;7(8):893-903. Epub 2017 Nov 13.

Animal Biochemistry Division, National Dairy Research Institute (NDRI), Karnal, Haryana 132001 India.

An electrochemical aptasensor for detection of trace amounts of aflatoxin M1 was developed. This required immobilization of aptamer on screen printed gold electrode comprising of working electrode, counter electrode and reference electrode and was achieved by sequentially layering dithiodipropionic acid, streptavidin and biotinylated-tetraethylene glycol-aptamer. Immobilization of aptamer was monitored by cyclic voltammetry. Read More

Green synthesis of silver nanoparticles: characterization and determination of antibacterial potency.

Appl Nanosci 2016;6:259-265. Epub 2015 Mar 20.

Centre of Advanced Study in Botany, School of Life Sciences, University of Madras, Guindy Campus, Chennai, 600 025 Tamil Nadu India.

Silver ions (Ag) and its compounds are highly toxic to microorganisms, exhibiting strong biocidal effects on many species of bacteria but have a low toxicity toward animal cells. In the present study, silver nanoparticles (SNPs) were biosynthesized using aqueous extract of as reducing agent and size of SNPs synthesized ranged between 15 and 47 nm. SNPs were characterized by UV-visible spectroscopy, scanning electron microscopy, transmission electron microscopy, X-ray diffraction and Fourier infrared spectroscopy, and analyzed for its antibacterial property against human pathogens.

Assessment by Ames test and comet assay of toxicity potential of polymer used to develop field-capable rapid-detection device to analyze environmental samples.

Appl Nanosci 2015;5(6):763-769. Epub 2014 Nov 2.

US Food and Drug Administration, Winchester Engineering and Analytical Center, Winchester, MA 01890 USA.

There is need for devices that decrease detection time of food-borne pathogens from days to real-time. In this study, a rapid-detection device is being developed and assessed for potential cytotoxicity. The device is comprised of melt-spun polypropylene coupons coated via oxidative chemical vapor deposition (oCVD) with 3,4-Ethylenedioxythiophene (EDOT), for conductivity and 3-Thiopheneethanol (3TE), allowing antibody attachment.
