Abstract
An electric-current biosensor has first and second supports, a pair of positive and negative electrodes on the first supports, an activity area covers the positive and negative electrodes, a pair of testing ports on two sides of the second support, and an electrode film mating with the activity area. The pair of testing ports force the sample to flow into the activity area and stops the sample from flowing outside the support along the surface thereof.
