Abstract
A biosensor is fabricated by forming a metal film over the surface of a substrate through evaporation, sputtering or by gluing a metal foil, then splitting the metal film into three regions, and forming a reagent layer on an area of measuring electrode and two counter-electrodes for placing a liquid sample on by providing a cover disposed over the splitted metal film. As neither of the electrodes are formed through conventional printing technology, the electrodes can be formed without dispersion. As a result, a precision biosensor having excellent response characteristics is implemented.
