Nanoparticles, such as noble metal nanoparticles, having improved stability against aggregation in aqueous solution are provided. In addition to having improved stability against aggregation, the nanoparticles are highly photostable. Also provided are aqueous solutions containing the stabilized nanoparticles, methods of making the stabilized nanoparticles, imaging methods and organisms employing the nanoparticles, and in vivo assays for screening and characterizing the toxicity and biocompatibility of the nanoparticles. |
