  • Optical feedback structures and methods of making
    Patent number: 8891575
    Abstract: An optical resonator can include an optical feedback structure disposed on a substrate, and a composite including a matrix including a chromophore. The composite disposed on the substrate and in optical communication with the optical feedback structure. The chromophore can be a semiconductor nanocrystal. The resonator can provide laser emission when excited.
    Type: Grant

  • Fluorescent sensor based on two fluorescent moieties, one of which is a semiconductor nanocrystal, and methods of using and making
    Patent number: 8313957
    Abstract: Binding an analyte can cause a change in fluorescence emission of a sensor. The change in fluorescence can be related to the amount of analyte present. The sensor can include a semiconductor nanocrystal linked to a fluorescent moiety. Upon excitation, the fluorescent moiety can transfer energy to the semiconductor nanocrystal, or vice versa.
