  • Patent number: 10823728
    Abstract: A method and system for analysis of protein interaction kinetics in microarray or whole-cell based formats includes positioning a sensor chip on a prism. The sensor chip is spotted with a plurality of target molecules. A movable printer head deposits a plurality of analyte droplets on predefined regions of the sensor chip surface. A light source transmits light through the prism to excite surface plasmon resonance on the sensor chip surface, whereby the plurality of target molecules bound to the upper surface are changing the SPR resonance angle and therefore the intensity of the reflected beam. A detector receives reflected light transmitted through the prism from the bottom surface. Signals from the detector are received and processed into kinetic data and microarray labeled data to determine molecular interactions and binding kinetic properties for the plurality of analyte droplets.

  • Patent number: 10408757
    Abstract: Method and system to remove background noise with a differential approach in optical imaging is disclosed. The differential approach moves the sample position laterally over a small distance, and a differential image is generated from the images recorded before and after the lateral translation. This approach can significantly improve the image quality of objects, including single DNA molecules, for label-free optical imaging techniques, such as surface plasmon resonance imaging. Disclosed imaging technique provides high-resolution genome-wide restriction maps of single DNA molecules.

  • Patent number: 7534610
    Abstract: A cell growth matrix for optimizing 3D organization nutrient delivery, controlling release of differentiation factors and facilitating attachment of cells to a scaffold Colloidal crystals and inverted colloidal crystals are used to form an ordered structure for use as a scaffold for tissue engineering. The porosity of the cell growth matrix may be modified by the selection of particles of appropriate diameter. Further, the surface of colloidal crystals can be easily modified to accommodate many organic species including biomolecules. Layer-by-layer materials are used for tissue engineering to control cell development by using sequential layering of bioactive species wherein the number and order of LBL layers deposited between layers containing a particular protein are controlled. LBL may also be used for timed release of bioactive species. Increased control differentiation factors release and control of cell attachments to the scaffold are achieved to better mimic natural tissue development.

  • Publication number: 20070189359
    Abstract: A nanoparticle fluorescence (or upconversion) sensor comprises an electromagnetic source, a sample and a detector. The electromagnetic source emits an excitation. The sample is positioned within the excitation. At least a portion of the sample is associated with a sensory material. The sensory material receives at least a portion of the excitation emitted by the electromagnetic source. The sensory material has a plurality of luminescent nanoparticles luminescing upon receipt of the excitation with luminance emitted by the luminescent nanoparticles changing based on at least one of temperature and pressure. The detector receives at least a portion of the luminance emitted by the luminescent nanoparticles and outputs a luminance signal indicative of such luminance. The luminescence signal is correlated into a signal indicative of the atmosphere adjacent to the sensory material.
