    摘要: A method of manufacturing a nanopatterned biophotonic structure includes forming a customized nanopattern mask on a substrate using E-beam lithography, providing a biopolymer matrix solution, depositing the biopolymer matrix solution on the substrate, and drying the biopolymer matrix solution to form a solidified biopolymer film. A surface of the film is formed with the nanopattern mask, or a nanopattern is machined directly on a surface of the film using E-beam lithograpy such that the biopolymer film exhibits a spectral signature corresponding to the E-beam lithograpy nanopattern. The resulting bio-compatible nanopatterned biophotonic structures may be made from silk, may be biodegradable, and may be bio-sensing devices. The biophotonic structures may employ nanopatterned masks based on non-periodic photonic lattices, and the biophotonic structures may be designed with specific spectral signatures for use in probing biological substances, including displaying optical activity in the form of opalescence.

    摘要: The present invention provides methods and systems for performing in-vivo flow cytometry to obtain desired information regarding one or more cell types of interest flowing through a subject's circulatory system. In one embodiment of the invention, a portion of the subject's circulating blood is illuminated with radiation having multiple wavelength components, and the backscattered radiation generated in response to the excitation radiation is detected at a plurality of scattering angles and analyzed to derive the desired information.
