▎ 摘　　要

NOVELTY - Process for constructing and applying an electrochemical biosensor based on graphene and biomaterials of Botryosphaeria rhodinaand Pycnoporus sanguineusinvolves (a) constructing electrochemical device, based on platform of nanostructured material (graphene) and biomaterials of B.rhodinaand P.sanguineus, and (b) characterizing the device in detection and quantification of guaiacol. USE - The process is useful for constructing and applying an electrochemical biosensor based on graphene and biomaterials of B.rhodina and P.sanguineus. ADVANTAGE - The process is simple and cost-effective to perform.
