Lipid bilayers are biomembranes common to cellular life and constitute a continuous barrier between cells and their environment. Understanding the interaction of nanoparticles with lipid bilayers is an important step toward predicting subsequent biological effects. In this study, we assessed the affinity of functionalized gold nanoparticles (Au NPs) with sizes from 5 to 100 nm… Read more »
Jonathan Posner gave an invited talk and Jeff Moran presented a poster at the microfluidics GRC in Waterville Valley, NH. They both presented work on electrokinetic locomotion of catalytic nanomotors.
Abstract: Mitchell originally proposed that an asymmetric ion flux across an organism’s membrane could generate electric fields that drive locomotion. Although this locomotion mechanism was later rejected for some species of bacteria, engineered Janus particles have been realized that can swim due to ion fluxes generated by asymmetric electrochemical reactions. Here we present governing equations,… Read more »
