Abstract
We report for the first time a rapid and high sensitive bio-sensing system by using magnetic beads and an array sensor consisted of MOS Hall elements. This system has been applied to immunoassay and successfully achieved the testing time of 3min and the minimum detection limit of 0.1 ng/ml for antigens.
