  • Compositions having a mixture of strongly plasmonic nanorods and exhibiting an extinction spectrum transparency window
    Patent number: 10317581
    Abstract: A composition includes a first population of strongly plasmonic nanorods and a second population of strongly plasmonic nanorods. The two populations each have a size range of the nanorods, creating a size range gap between the two populations. This size range gap creates a transparency window that can be seen in an extinction spectrum of the composition, which is characterized by the sizes of the nanorods in both populations. The composition may be included in a filter providing a transparency to a defined wavelength characterized by the size range gap of the nanorods.
    Type: Grant
    Filed: March 27, 2015
    Date of Patent: June 11, 2019
    Assignee: Ohio University
    Inventor: Alexander Govorov

  • Nanoparticle assemblies with molecular springs
    Patent number: 8080183
    Abstract: A nanoscale sensing device from different types of nanoparticles (NPs) and nanowires (NWs) connected by molecular springs. The distance between the nanoscale colloids reversibly changes depending on conditions or analyte concentration and can be evaluated by fluorescence measurements.

  • PHOTOACTIVE NANOSTRUCTURE AND METHOD OF MANUFACTURING SAME
    Publication number: 20110012096
    Abstract: A nanostructure comprising at least one semiconductor nanoparticle bound to a photocatalytic unit of a photosynthetic organism is disclosed. The nanoparticle and a binding between the nanoparticle and the photocatalytic unit are selected such that transfer of electrons from the photocatalytic unit to the nanoparticle is prevented or suppressed relative to transfer of excitons from the nanoparticle to the photocatalytic unit. Uses of same and methods of fabricating devices with same are also disclosed. Nanostructures comprising electrically conductive nanoparticles are also disclosed.
