Abstract
An electrochemical biosensor using a sensing system includes a working electrode including an active surface modified through a linker; and an auxiliary electrode. The sensor has a high current value compared with an existing sensor and retains excellent stability and sensitivity, and thus can be expected to be easily used for sensing various kinds of biomaterials.
