Abstract

Conducting polymer hydrogel is fabricated atop gold or ITO electrodes and is functionalized with monoclonal antibodies. Binding of interferon-γ molecules causes redox properties of conductive hydrogel to change in a concentration-dependent fashion without the need for washing or sample handling steps. This conductive hydrogel remains functional in a fouling media such as whole blood.
