Abstract: Disclosed herein are methods and compositions of nanoparticles having one or more layers of organic coating. In some embodiments, a nanoparticle comprises a core/shell nanocrystal comprising a first coating layer comprising a plurality of organic molecules, and a second organic coating layer surrounding the first organic coating layer, wherein the second coating layer comprises a plurality of organic molecules. Further, the organic molecules of the second coating layer are intercalated between the organic molecules of the first coating layer.

Abstract: The present invention is directed to compositions comprising conglomerated semiconductor nanocrystals, methods of making conglomerated semiconductor nanocrystals, and methods of using conglomerated semiconductor nanocrystals. Conglomerated semiconductor nanocrystals can be prepared by agitation in solutions comprising one or more nonpolar solvents, or by crosslinking to a variety of polymers. The invention also includes methods of preparing hydrophilic conglomerated semiconductor nanocrystals by enclosing them within a hydrophilic polymer “cage.” Conglomerated semiconductor nanocrystals are useful in a variety of fluorescence based detection systems.
