Electrochemical myoglobin biosensor based on graphene–ionic liquid–chitosan bionanocomposites: Direct electrochemistry and electrocatalysis

Electrochemical performance of myoglobin based on TiO2-doped carbon nanofiber decorated electrode and its applications in biosensing

“…Due to the commercial availability and welldocumented structure of Mb, studies of DET with Mb have received considerable attention. 16,17 Many methods have been employed to improve the electron transfer efficiency of Mb, such as mediators, promoters or nanomaterials, which open new approaches in the electrochemistry of redox proteins and in applications of biosensors or biocatalysis.…”

Nitrite detection in meat products samples by square-wave voltammetry at a new single walled carbon naonotubes – myoglobin modified electrode

“…It is well-known, that heme proteins often undergo a pH dependent conformational change, because the pH value changes of the bulk buffer solution can influence the microstructure of proteins, causing changes in the electrochemical behaviors of redox proteins by modulating the accessibility of water to the heme cavity of myoglobin or by protonation of the heme iron-bound proximal histidine and/or the distal histidine in the heme cavity (Ruan et al, 2012;Turdean et al, 2006).…”

Sensitive electrochemical determination of oxalic acid in spinach samples by a graphene-modified carbon ionic liquid electrode

“…The HPPF 6 -based CILE was prepared based on the reported procedure [33] and the surface of CILE was polished on a weighing paper just before use. Electroreduction is a new method for the formation of GR nanosheets directly on the electrode surface with simple procedure and green nature, which has been used for the electrode modification [31].…”
