Graphene nanoplatelets are shown to electrocatalyse the oxidation of dopamine. Single entity measurements (‘nano-impacts’) coupled with microdisc voltammetry and UV-visible spectroscopy reveal that adsorption of dopamine and its oxidised product on the graphene nanoplatelets is the key factor causing the observed catalysis. Genetic implications are drawn both for the study of catalysts in general and for graphene nanoplatelets in particular.

冲击电化学表明，石墨烯纳米片通过吸附来催化多巴胺的氧化

石墨烯纳米片被显示为电催化多巴胺的氧化。单实体测量（“纳米碰撞”）与微盘伏安法和紫外可见光谱法相结合，揭示多巴胺及其氧化产物在石墨烯纳米片上的吸附是引起所观察到的催化作用的关键因素。遗传意义既适用于一般催化剂的研究，又适用于石墨烯纳米片的研究。
