  • Publication number: 20210108248
    Abstract: The present disclosure relates to a cartridge, detection module, system, and kit for cell and particle detection and analysis. Devices disclosed herein may include at least an optical source, a fluidic chip, and a detection module, wherein the sample flows within the fluidic chip past a detection window, where the cells or particles are imaged by an image acquisition and analysis module that may include an optical detector. The image acquisition and analysis module may count the cells or particles of interest in real-time, or near real-time, or the module may capture images of the cells in order to analyze the sample from combined images at a later time.

  • Publication number: 20140170679
    Abstract: The present invention is a method and a system of cell detection and analysis. The present invention may incorporate at least an optical source, a fluidic chip and a detection module. Cells may be caused to flow within the fluidic chip and specifically past a detection window section accessible by the optical source. The flowing cells may be identified and/or analyzed. The detection module may specifically count the cells of interest as they flow past the detection window section of the chip. The detection module may further be operable to generate or otherwise capture images of the cells as they flow past the window and to use these images collectively for the purpose of analyzing the cells. The present invention may be portable and operable in remote locations.
