Plasmonic biocompatible silver–gold alloyed nanoparticles†
Abstract
The addition of Au during scalable synthesis of nanosilver drastically minimizes its surface oxidation and leaching of toxic Ag+ ions. These biocompatible and inexpensive silver–gold nanoalloyed particles exhibit superior plasmonic performance than commonly used pure Au nanoparticles, and as such these nanoalloys have great potential in theranostic applications.
