▎ 摘　　要

NOVELTY - Biosensor based on N-graphene nanoribbons-gold platinum nanoclusters, prepared by using glassy carbon electrode as the working electrode and modifying with N-graphene nanoribbons-gold platinum nanocluster composite, is claimed. USE - Used as a biosensor based on N-graphene nanoribbons-gold platinum nanoclusters. ADVANTAGE - The method: enables preparing the biosensor with improved selectivity and sensitivity, reduced detection time, reduced detection cost, high sensitivity and high selectivity, in a rapid and cost efficient manner. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing biosensor based on N-graphene nanoribbons-gold platinum nanoclusters; and (2) detecting ascorbic acid, dopamine and uric acid of biosensor based on N-graphene nanobelt-gold platinum nanocluster.
