A noncovalent nanohybrid of cobalt tetraphenylporphyrin (CoTPP) with chemically reduced graphene oxide (CRGO) was prepared through π–π stacking interaction between CRGO and CoTPP. The hybrid (CoTPP-CRGO) was characterized by UV–vis spectroscopy, Raman spectroscopy, and atomic force microscopy. The electrochemical behaviors of ascorbic acid (AA), dopamine (DA), and uric acid (UA) at CoTPP-CRGO modified...
A nanoscale hybrid of chemically reduced graphene oxide (CRGO) with ferrocene (Fc) was prepared through π–π stacking interaction between Fc and CRGO. FT-IR, Raman spectroscopy, SEM and cyclic voltammetry were utilized to characterize the nanohybrid of Fc with CRGO (Fc-CRGO). Fc-CRGO exhibited good stability and greatly improved electron-transfer behavior. Fc-CRGO and HRP were casted on the surfaces...
