Rapid detection of bacteria and viruses in multiple liquid media

[Category : - Food- HEALTH]
[Viewed 1001 times]

The present invention is directed to a method and apparatus for an immunoassay technique that uses amperometric measurements to rapidly analyze different pathogenic microorganisms, including bacteria, viruses, toxins, and parasites and chemical compounds using a disposable element. In accordance with one aspect of the present invention, at least one conductive immunosorbent is used to provide support for antibody immobilization and placed on the top of the working electrode; it could also be used by itself as a working electrode. This immunosorbent or powder can be fabricated of conductive material or nonconductive material over which a conductive material is coated. A membrane cover of the working electrode forms a fluidic chamber having a pore size that is suited to the particular application to insure no contact between the working electrode and counter or silver electrode. The immunoassay can be automated using microprocessor control to reduce the amount of human intervention.
