  • Publication number: 20150322499
    Abstract: A method for analyzing a target molecule using thermophoresis is provided. The method of the invention comprises (1) providing a solution containing samples, labeled molecules, and probe particles; (2) providing a temperature control system to create a temperature gradient within the solution; (3) detecting the expression level of the labeled molecule in a predetermined area and a contrast area; and (4) analyzing the difference in the expression level of the labeled molecules between the predetermined area and the contrast area to determine the result. In another embodiment of the invention, the solution contains samples and “labeled molecule-reactant-probe particle” complexes. In the present invention, the probe particles are used to increase the difference in thermophoresis between the molecular complexes and the free labeled molecules, which can improve the accuracy of the quantification of the target molecules using thermophoresis.

  • Patent number: 9057825
    Abstract: A plurality of photonic crystal resonator optical trapping apparatuses and a plurality optical trapping methods using the plurality of photonic crystal resonator optical trapping apparatuses include located and formed over a substrate a photonic waveguide that is coupled (i.e., either separately coupled or integrally coupled) with a photonic crystal resonator. In a particular embodiment, the photonic waveguide and the photonic crystal resonator comprise a monocrystalline silicon (or other) photonic material absent any chemical functionalization.

  • Patent number: 6914525
    Abstract: The invention advantageously provides an alert system and method for geographic or natural disasters that utilize a telecommunications network for monitoring geographic data in disaster-prone areas and accordingly issuing warnings against potential disasters to people inside the monitored area. An alert system according to a preferred embodiment of the invention comprises a telecommunications service network, one or more wireless sensor modules and a control center. The telecommunications network according to this particular embodiment includes service coverage over the monitored areas. The wireless sensor modules are installed to selected locations inside monitored areas. Each of the sensor modules further comprises at least one sensor for collecting geographic or geodetic data and a wireless communications unit for sending collected geographic data to the control center via the telecommunications network.
