title: Electrical, enzymatic graphene biosensing of 5-aminosalicylic acid.
abstract: We present an electrical biosensing of 5-aminosalicylic acid (5-ASA) based on a peroxidase-immobilized graphene sensor on a microfluidic paper. The sensor shows a sensitive detection range from 0.5 to 20 μM and a total measuring time of 2 min with a simple fabrication procedure.
