  • Lipid-coated nucleic acid nanostructures of defined shape
    Patent number: 9717685
    Abstract: The invention provides nanoparticles containing a nucleic acid nanostructure, of defined shape and size, linked to a hydrophobic moiety and coated by lipids, compositions comprising the nanoparticles, and methods of producing and methods of using the nanoparticles.
    Type: Grant
    Filed: March 13, 2013
    Date of Patent: August 1, 2017
    Assignee: President and Fellows of Harvard College

  • Synthesis of fluorescent noble metal nanoparticles
    Patent number: 9395371
    Abstract: A process for the production of fluorescent nanoparticles selected from noble metal or silica nanoparticles. Noble metals or silica nanoparticles provide a platform to which fluorophores and other detection molecules can be added. The fluorescent nanoparticles can be used as regents, diagnostic assays and in the tracking or targeting of tumors.

  • SYNTHESIS OF FLUORESCENT NOBLE METAL NANOPARTICLES
    Publication number: 20130183665
    Abstract: A process for the production of fluorescent nanoparticles selected from noble metal, silica or polymer nanoparticles which comprises: 1. A process for the production of fluorescent nanoparticles selected from noble metal or silica nanoparticles which comprises: (1) providing a platform of nanoparticles; (2) covering the surfaces of the nanoparticles to saturation with thiol-terminated polymers by one of the following methods: 1. mixing the nanoparticles with methoxy-(polyethylene glycol)-thiol and biotin-(polyethylene glycol)-thiol; 2. mixing the nanoparticles with fluorescently-labeled methoxy-(polyethylene glycol)-thiol and/or biotin-(polyethylene glycol)-thiol 3. coordinating thiol and biotin thiol to the surfaces of the nanoparticles by a non-covalent bond; and 4.
