  • Publication number: 20240027868
    Abstract: An optical phased array (OPA) radiator includes a plurality of unit radiators configured to serve as optical waveguides, each of the unit radiators being made of a silicon material and each having a predetermined length, where the unit radiators are disposed in parallel; a cladding portion configured to cover the plurality of unit radiators; and a plurality of electrodes arranged in parallel with the plurality of unit radiators on the cladding portion, where the plurality of electrodes are arranged so as not to overlap the plurality of unit radiators in a vertical direction. A beam radiated through the unit radiators using a phased array can be efficiently vertically steered.

  • Publication number: 20220298513
    Abstract: The present invention relates to a method of identifying an intracellular secretory protein or tissue-specific secretory protein, by using a proximity labeling system. When the method according to the present invention is used, it is possible to clearly identify an intracellular secretory protein and to dynamically track the spatiotemporal dynamics of a secretory protein secreted from a specific tissue in a living subject such that it can be effectively utilized for the research on endocrine signals between tissues, and particularly, since it can be applied in situ, the scope of application can be further expanded. Therefore, the present invention can be applied to various disease models or tissues to discover new biomarkers and therapeutic target proteins associated with diseases.

  • Patent number: 11329725
    Abstract: A device system for constituting a 3D image sensor based on optical phased array is provided. The device system includes an optical modulator that is integrated on the same photonic integrated circuit (PIC) chip as a laser diode array with different output wavelengths and a multiplexer for transmitting an optical wave having a wavelength selected from the laser diode array to an optical waveguide and modulates the optical wave into a specific optical signal, an optical phased array that radiates the optical signal received via an optical switch to the free space using a tunable transmit and receive (TRx) antenna array, and a photodetector that converts an Rx optical signal received by a Tx optical signal transmitted via the optical phased array into an electrical signal.

  • Patent number: 9624524
    Abstract: The application discloses methods, materials, and compositions for the labeling of molecules, for example, proteins, in living cells or in subcellular compartments of living cells. In particular, the application relates to proteomic analysis methods; materials and compositions and means based on direct tagging of unknown proteins with tagging enzymes (such as biotin ligase or a peroxidase) within the vicinity of a tagging substrate (such as a tyramide) within living cells, with optional targeting to specific subcellular locations by expression of genetic constructs.
