Abstract

original image

Surface functionalization: Complete detoxification of gold nanorods was achieved by manipulating the position in the stability map between surface-adsorbing polyethylene glycol (PEG) and destabilizing ethanol (see picture). This robust procedure complements studies related to the effects of shape when contemplating the nanoparticle–cell interaction.
