Engineering safer-by-design silica-coated ZnO nanorods with reduced DNA damage potential
Sotiriou, Georgios; Wright, Christa Young; Murdaugh, Kimberly; Darrah, Thomas H.; Pyrgiotakis, Georgios; Elder, Alison; Brain, Joseph David; Demokritou, Phil K. (Royal Society of Chemistry (RSC), 2014)Zinc oxide (ZnO) nanoparticles absorb UV light efficiently while remaining transparent in the visible light spectrum rendering them attractive in cosmetics and polymer films. Their broad use, however, raises concerns ... -
High-Throughput Screening Platform for Engineered Nanoparticle-Mediated Genotoxicity Using CometChip Technology
Watson, Christa; Ge, Jing; Cohen, Joel; Pyrgiotakis, Georgios; Engelward, Bevin P.; Demokritou, Philip (American Chemical Society, 2014)The likelihood of intentional and unintentional engineered nanoparticle (ENP) exposure has dramatically increased due to the use of nanoenabled products. Indeed, ENPs have been incorporated in many useful products and have ... -
Optimization of a nanotechnology based antimicrobial platform for food safety applications using Engineered Water Nanostructures (EWNS)
Pyrgiotakis, Georgios; Vedantam, Pallavi; Cirenza, Caroline; McDevitt, James; Eleftheriadou, Mary; Leonard, Stephen S.; Demokritou, Philip (Nature Publishing Group, 2016)A chemical free, nanotechnology-based, antimicrobial platform using Engineered Water Nanostructures (EWNS) was recently developed. EWNS have high surface charge, are loaded with reactive oxygen species (ROS), and can ... -
Real-Time Nanoparticle–Cell Interactions in Physiological Media by Atomic Force Microscopy
Pyrgiotakis, Georgios; Blattmann, Christoph O.; Demokritou, Philip (American Chemical Society, 2014)Particle–cell interactions in physiological media are important in determining the fate and transport of nanoparticles and biological responses to them. In this work, these interactions are assessed in real time using a ...
