This paper describes the direct electrochemistry and electrocatalysis of myoglobin immobilized on graphene‐cetylramethylammonium bromide (CTAB)‐ionic liquid nanocomposite film on a glassy carbon electrode. The nanocomposite was characterized by transmission electron microscopy, scanning electron microscopy, X‐ray photoelectron spectroscopy, and electrochemistry. It was found that the high surface...
Graphene, emerging as a true 2‐dimensional material, has received increasing attention due to its unique physicochemical properties (high surface area, excellent conductivity, high mechanical strength, and ease of functionalization and mass production). This article selectively reviews recent advances in graphene‐based electrochemical sensors and biosensors. In particular, graphene for direct electrochemistry...
A hybrid organic–inorganic nanocomposite film of chitosan/sol–gel/multi-walled carbon nanotubes was constructed for the immobilization of horseradish peroxidase (HRP). This film was characterized by scanning electron microscopy. Direct electron transfer (DET) and bioelectrocatalysis of HRP incorporated into the composite film were investigated. The results indicate that the film can provide a favorable...
