Abstract
Disclosed is a porous membrane built-in biosensor comprising (a) at least one substrate; (b) an electrode layer patterned on the substrate, consisting of an electrode system and a circuit connector; (c) an insulator, formed on parts of the electrode layer, for electrically separating the electrode system from a circuit connector; and (d) a porous membrane via the insulator on the electrode system, wherein, when a whole blood sample is introduced to the biosensor, the whole blood sample is separated into its components during the chromatographic motion through the porous membrane so that only blood plasma can be contacted with the electrode system. The porous membrane built-in biosensor is provided with a sample inlet, which allows samples to be introduced in a constant quantity to the biosensors porous membranes without pretreatment.
