Characterization, direct electrochemistry, and amperometric biosensing of graphene by noncovalent functionalization with picket-fence porphyrin.

本文制备了还原氧化石墨烯（RGO），并通过π–π非共价相互作用将其与水溶性栅栏式卟啉铁5,10,15,20-四[aaaa-2-三甲基铵甲基苯基]卟啉铁(III)五氯化物（FeTMAPP）功能化。利用原子力显微镜、透射电镜、接触角、荧光、拉曼和紫外-可见吸收光谱对FeTMAPP/RGO纳米复合材料进行表征。由于FeTMAPP带正电荷，...
