| 20110220844 | SULFONATE MODIFIED NANOCRYSTALS - A nanoparticle having one or more phosphonates or phosphinate ligands on their surface can be converted into nanoparticles with sulfonate ligands on their surface, by contacting the phosphonate-containing nanoparticles with a silylsulfonate reagent. Such nanoparticles are activated toward reactions with nucleophilic groups; thus the method provides activated nanoparticles, and methods of making and using them to produce modified nanoparticles. | 09-15-2011 |
| 20110223110 | STABLE INDIUM-CONTAINING SEMICONDUCTOR NANOCRYSTALS - Nanocrystals having an indium-based core and methods for making them and using them to construct core-shell nanocrystals are described. These core-shell nanocrystals are highly stable and provide higher quantum yields than known nanocrystals of similar composition, and they provide special advantages for certain applications because of their small size. | 09-15-2011 |
| 20110226991 | STABLE NANOPARTICLES AND METHODS OF MAKING AND USING SUCH PARTICLES - A population of nanoparticles is disclosed. The population is comprised of a plurality of core/shell nanocrystals, each including: a semiconductor core, an intermediate semiconductor shell layer disposed over the semiconductor core, an external semiconductor shell layer disposed over the intermediate semiconductor shell layer, and a hydrophilic organic layer in direct contact with the external semi-conductor shell layer. The population of nanoparticles has a α | 09-22-2011 |
| 20110226995 | COMPOSITIONS AND METHODS FOR FUNCTIONALIZING OR CROSSLINKING LIGANDS ON NANOPARTICLE SURFACES - This disclosure provides novel ways to modify/functionalize, including crosslink, ligands in the surface coating or molecules in other coatings on a nanoparticle, by using radical addition reactions to add a reactant group onto a ligand/molecule of a nanoparticle. Examples include using a functionalized benzophenone that can be attached or crosslinked to a ligand in the surface coating of a nanocrystal by photochemically-initiated radical addition. | 09-22-2011 |
| 20110256404 | NANOCRYSTALS WITH FUNCTIONAL LIGANDS - Coated fluorescent semiconductor nanoparticles having an organic surface layer of multi-functional surface ligands that include a nanocrystal binding center and one or more covalently attached functional groups or reactive functional groups are described as well as water-dispersible nanoparticles having an organic surface layer or multi-functional surface ligands and methods for the preparation and use of such coated nanoparticles. | 10-20-2011 |
| 20110300076 | METHODS FOR PREPARATION OF ZnTe NANOCRYSTALS - Nanocrystals having a ZnTe core and methods for making and using them to construct core-shell nanocrystals are described. These core-shell nanocrystals are highly stable and provide quantum yields and stability suitable for applications such as flow cytometry, cellular imaging, and protein blotting, medical imaging, and other applications where cadmium toxicity is an issue. | 12-08-2011 |
| 20110306079 | WATER-DISPERSABLE NANOPARTICLES - Provided herein are methods for making water-soluble nanoparticles comprising a core/shell nanocrystal that is coated with a surface layer comprising enough hydrophilic ligands to render the nanoparticle water soluble or water dispersable. Methods for crosslinking molecules on the surface of a nanoparticle, which methods can be used on the above water-soluble nanoparticles also are provided. Nanoparticle compositions resulting from these methods are also provided. | 12-15-2011 |
| 20110315927 | METHODS FOR PREPARATION OF NANOCRYSTALS USING A WEAK ELECTRON TRANSFER AGENT AND MISMATCHED SHELL PRECURSORS - Methods for preparing core/shell nanocrystals are provided, using mismatched shell precursors and an electron transfer agent to control the nucleation and growth phases of particle formation. | 12-29-2011 |
