  • Patent number: 8586371
    Abstract: A sensor device includes an optical limiting structure including a metal layer with at least one metal particle having a size no greater than about 1500 nanometers, and a phase-change material layer disposed adjacent at least a portion of the metal layer, the phase-change material layer including a phase-change material, and a dendritic-metal layer disposed over at least a portion of the phase-change material layer of the optical limiting structure, the dendritic-metal layer including an organic compound including branching chain amino acid groups attached to a metal structure. The optical limiting structure is configured to transition from a first optical state to a second optical state when the phase-change material is heated above a critical temperature, with transmittance of light at a predetermined wavelength through the optical limiting structure being lower at the second optical state of the optical limiting structure in relation to the first optical state of the optical limiting structure.
    Type: Grant

  • Patent number: 7545490
    Abstract: A flow cell apparatus is provided comprising a body having a first surface, an inlet port and an outlet port. A channel is provided in the body having a first end and a second end. In one embodiment, the channel is sized so as to have a depth that allows for sufficient excitation and illumination of solutions or particles contained in a liquid to be analyzed. The inlet port is coupled to the first end of said channel and the outlet port is coupled to the second end of said channel. A window of optically transparent material overlies at least a portion of the channel to provide optical access to the liquid in the channel.
