assembling of copper nanoparticles in graphene quantum dots functionalized by biowaste for in situ electrochemical detection of hydrogen peroxide

Hydrogen peroxide (h2o2) is a very simple molecule in nature but has been widely used in pharmaceutical, clinic, environmental, mining, textile, paper, food manufacturing and chemical industries because of its strong oxidizing and reducing properties [1, 2]. this work describes a convenient and effective strategy to construct a highly sensitive amperometric biosensor for the detection of h2o2 based on copper nanoparticles in graphene quantum dots functionalized by biowaste (chicken feet yellow membrane) nano composite (cu/ cfym/gqds/gce).
