ABSTRACT:
A biosensor for detecting contents of biochemical components in a sample, comprising an electrically insulating substrate, a working electrode disposed on said substrate, a reference electrode disposed on said substrate, which is spaced from said working electrode, a reaction layer disposed on said working electrode and said reference electrode, wherein said reaction layer and said electrodes form a reaction area for reacting with the sample, an electrically insulating layer disposed on said substrate and having an opening for receiving the sample, wherein said opening exposes a portion of said reaction area and the end of said opening is located at the edge of the biosensor; and a reticular covering layer which covers said opening and the end of said opening of said insulating layer wherein said reticular layer and said insulting layer form a sampling area from said reticular covering area to the edge of said biosensor.
