  • Sensing device and method for rapidly determining concentrations of microbial organisms using interfacial photo-voltages
    Patent number: 7892495
    Abstract: A system for detecting a wide range of microbial organisms, including virus, and determining concentrations in near real-time to determine titer, without the requirement to grow micro-organisms includes an electrometer configured to measure photo-induced interfacial voltages and an electrode assembly with a substrate and at least one electrode on a surface of the substrate electrically coupled to the electrometer. An attachment factor is applied to an exposed surface of each electrode. The attachment factor is effective for interaction with the microbial organism. A transparent vessel for containing the electrolytic solution is provided. The microbial organism may be contained in the electrolytic solution or applied to the coated electrode before being submerged in the electrolytic solution.
    Type: Grant
