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.

石墨烯纳米片被证明可电催化多巴胺的氧化。单实体测量（“纳米撞击”）结合微盘伏安法和紫外可见光谱表明，多巴胺及其氧化产物在石墨烯纳米片上的吸附是导致观察到的催化作用的关键因素。这对一般催化剂的研究，尤其是对石墨烯纳米片的研究都具有遗传学意义。
