Latest Patents
One of his latest patents focuses on evanescent wave background fluorescence and absorbance detection. This invention aims to enhance the utility of intracellular fluorescence and absorbance measurements for controlling fermentation and cell culture. It corrects for background fluorescence of the media and allows for the measurement of fluorescence or absorbance in the presence of suspended cells or particles. The technology utilizes the characteristics of the evanescent wave at the surface of an optic waveguide, which penetrates into the less dense medium to a depth of about 1/2 wavelength. This method effectively separates the fluorescence or absorbance of the media from that of the cells. The apparatus disclosed includes the use of an optical fiber to generate the evanescent wave and a flat plate waveguide for data collection. Another significant patent involves the electrochemical determination of hematocrit, providing a method for measuring hematocrit using an electrochemically detectable marker.
