- Description:
- Gold nanoparticles (AuNPs) display unique characteristics compared to their macro-counterparts that are dependent on shape, size, and attached surface molecules. Methods have been developed to precisely control both size and shape of AuNPs for specific applications. The biocompatibility, plasmonic properties, and ease of functionalization with thiolated molecules, make gold nanoparticles...
