文摘

An electrochemical sensor based on well-dispersed graphene and MoS2 was prepared by a convenient modification process. Graphene can enhance the electrochemical response intensity of dopamine and MoS2 served as an amplification element. High selectivity, good stability, wide linear range and high sensitivity.
