  • Patent number: 11391622
    Abstract: An optical fiber sensing system with reduced spatial resolution and noise for multiple applications and method of operating same that employs a coherent receiver configured to detect and digitize both I and Q signals in two polarizations and performs signal beating in a digital signal processor (DSP) using the polarization-diverse signals to obtain beating results for multiple polarization state pairs that effectively reduces polarization induced fading effect(s) while providing faster sensing speed(s) and more efficient filtering. Since Rayleigh signals are captured in two orthogonal polarizations, four beating products are determined at once in the DSP and all are used for fiber strain determination thereby avoiding polarization fading.

  • Patent number: 11280727
    Abstract: Systems and methods for sensing vibrational absorption induced photothermal effect via a visible light source. A Mid-infrared photothermal probe (MI-PTP, or MIP) approach achieves 10 mM detection sensitivity and sub-micron lateral spatial resolution. Such performance exceeds the diffraction limit of infrared microscopy and allows label-free three-dimensional chemical imaging of live cells and organisms. Distributions of endogenous lipid and exogenous drug inside single cells can be visualized. MIP imaging technology may enable applications from monitoring metabolic activities to high-resolution mapping of drug molecules in living systems, which are beyond the reach of current infrared microscopy.

  • Patent number: 11255806
    Abstract: Described are interdigitated electrodes, which may optionally be plasmonic, useful for in vitro biosensing applications. Such devices may significantly reduce undesired background noise by separating the excitation source (light) from the detection signal (current), and thereby, leading to higher sensitivity for bioanalysis compared with conventional interdigitated electrodes. Also described are methods of making such interdigitated electrodes, which allow a substrate, which may optionally be plasmonic, to be tuned not only to maximize the targeted interaction of the cells with the nanoscale geometry, but also for the excitation wavelength to minimize biological sample interference.
