Fabrication of Fragment Antibody–Enzyme Complex as a Sensing Element for Immunosensing
Antibody–enzyme complexes (AECs) are ideal molecular recognition elements for im-munosensing applications. One molecule possesses both a binding ability to specific targets and catalytic activity to gain signals, particularly oxidoreductases, which can be integrated into rapid and sensitive electrochemical measurements. The development of AECs using fragment antibodies rather than intact antibodie
