U55: Electrochemiluminescence Immunosensor

The present invention discloses an electrochemiluminescence (ECL) immunosensor that includes nanocomposite of gold nanoparticles-doped carbon nano-onions and chitosan-modified quantum dots screen-printed electrode for detection of analytes and proteins in a biological sample. The immunosensor can detect β2 microglobulin in serum and urine samples.

A low cost, highly sensitive immunosensor available for use in rapid point-of-care detection and quantification of β2M in serum and urine.
