Patent number: 7588827Abstract: Nanoparticles, methods of preparation thereof, and methods of detecting a target molecule using embodiments of the nanoparticle, are disclosed. One embodiment of an exemplary nanoparticle, among others, includes a surface-enhanced Raman spectroscopic active composite nanostructure. The surface-enhanced Raman spectroscopic active composite nanostructure includes a core, at least one reporter molecule, and an encapsulating material. The reporter molecule is bonded to the core. The reporter molecule is selected from: an isothiocyanate dye, a multi-sulfur organic dye, a multi-heterosulfur organic dye, a benzotriazole dye, and combinations thereof. The encapsulating material is disposed over the core and the reporter molecule. After encapsulation with the encapsulating material, the reporter molecule has a measurable surface-enhanced Raman spectroscopic signature.Type: GrantFiled: August 17, 2004Date of Patent: September 15, 2009Assignee: Emory UniversityInventors: Shuming Nie, William Doering

Patent number: 7585564Abstract: Ligand compositions for use in preparing discrete coated nanostructures are provided, as well as the coated nanostructures themselves and devices incorporating same. Methods for post-deposition shell formation on a nanostructure and for reversibly modifying nanostructures are also provided. The ligands and coated nanostructures of the present invention are particularly useful for close packed nanostructure compositions, which can have improved quantum confinement and/or reduced cross-talk between nanostructures.Type: GrantFiled: February 13, 2007Date of Patent: September 8, 2009Assignee: Nanosys, Inc.Inventors: Jeffery A.

Patent number: 7582354Abstract: A material composition comprises, on the one hand, a particulate material and, on the other hand, a binder which is provided as a coating on the material particles. The binder has at least two solid phases (13, 14), of which one harder phase (14) is configurationally stable and a softer phase (13) is plastic and readily deformable at temperatures below the melting point of the binder. A method for producing the above material comprises the steps that at least two components included in the binder are melted and mixed, whereafter kneading takes place during cooling. The material composition is usable, for example, as a play material, educational material, for sculptures or prototypes or as landscape architectonic material.Type: GrantFiled: June 29, 2005Date of Patent: September 1, 2009Assignee: Ramlat Ltd.Inventors: Jonas Modell, Staffan Thuresson
