US Patent 7153703 - Nanoparticle with Dendron Ligand Coating

Nanocrystals have very useful optical properties which can be tuned according to their size. However, they are also subject to oxidation that can hinder these optical properties. This patent from the University of Arkansas teaches using dendron ligands (hyper branched organic molecules) to avoid such oxidation. Claim 1 reads:

1. A nanoparticle composition comprising: a nanoparticle coated with a plurality of dendron ligands covalently bound to a surface of the nanoparticle.
