Study of detection method for collagenase enzyme reaction using two dimensional electrochemical sensor

摘要

This paper addresses the assay of collagenase activity using Light Addressable Amperometric Sensor (LAAS). The redox current of LAAS was reduced by deposited collagen layers and recovered by collagenase solution. The collagen layers on the LAAS is considered to be broken down by collagenase. We expect an application of LAAS to activity evaluation.
