An opposing electrode sensor with the activator and the electrochemical thrombin substrate coated on opposing surfaces of the working electrode and the counter electrode
An opposing-electrode sensor comprising a working electrode, a counter electrode, an activator and an electrochemical thrombin substrate. The activator and the electrochemical thrombin substrate are coated on opposing surfaces of the working electrode and the counter electrode. The sensor detects cleavage of the electrochemical thrombin substrate in the presence of a sample.
