AMPEROMETRIC BIOSENSOR FOR DETERMINING PERCHLOROETHYLENE () CONTENT IN WATER, AND ANALYSIS METHOD BY USING THIS SENSOR

摘要

The invention relates to a process for making a biosensor meant to determine the perchloroethylene content of water. According to the invention, the process consists in depositing, coat by coat, 4.2 mg of bimetallic Pt@Au nanoparticles, sonicated for 60 min, onto the carbon working electrode of a screen printed electrochemical cell, followed by depositing 10 μl of Chlamydomonas reinhardtii whole cells, so as to provide an amount of chlorophyll A of 17 ng/electrode.
