Impedance Immunosensor

A sensitive label-free and contactless impedance immunosensor is developed for the real-time interaction investigation between a cancer biomarker carcinoembryonic antigen (CEA) and its antibody CEA 5909. The immunosensor is proved to have a specific binding process between CEA and CEA 5909 with a detection limit of 100 fg mL−1in PBS.
