  • Patent number: 11422134
    Abstract: Disclosed herein are example embodiments of a transformative sensor apparatus that is capable of detecting and quantifying the presence of a substance of interest such as a specified bacteria within a sample via changes in impedance exhibited by a detection electrode array. In an example embodiment, sensitivity is improved by including a focusing electrode array in a rampdown channel to focus a concentration of the substance of interest into a detection region. The focusing electrodes include an opposing pair of electrodes in a rampdown orientation. The focusing electrode may also include tilted thin film finger electrodes extending from the rampdown electrodes. In another example embodiment, trapping electrodes are positioned to trap a concentration of the substance of interest onto the detection electrode array.

  • Patent number: 11150244
    Abstract: Provided are novel methods for screening and testing for pathogens in food, water, and bodily fluids using methods that are faster to complete than conventional methods of culturing and plating that require lengthy times in properly equipped labs. The invention utilizes specific, rapid and sensitive optical detection to capture small concentrations of the target bacteria and render them amenable for detection with various specific synthesis binding agents approaches. The technique merges capture and detection steps with quantification unit suitable to provide results in a relatively shorter time current detection methods.
