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

Abstract

A new biosensing strategy based on a TiO2-doped carbon nanofiber (CNF) composite modified electrode was developed.

Electrocatalytic Properties of Immobilized Heme Proteins: Basic Principles and Applications

“…In physiological conditions myoglobin contains a single ferrous heme b. [63,71,162,180] In these environments, unfolding of the protein cannot be totally ruled out, and the use of the sole Soret band could be insufficient to assess the folding state of the protein. Hemoglobin (Hb) is a globular protein whose quaternary structure consists of four subunits.…”

Carbon Nanohybrids for Advanced Electronic Applications

“…CNFs are widely used in nanoelectronic applications due to their 1D architecture, large surface area, and good conductivity. [ 117 ] The exclusive basal graphite planes and edge planes of CNFs mean that their surfaces are easily modified or functionalized. Thus, they can be used to create functional hybrid CNF‐based nanomaterials for numerous advanced electronic applications.…”

Graphene impregnated electrospun nanofiber sensing materials: a comprehensive overview on bridging laboratory set-up to industry

“…A variety of approaches have been exploited, including electrochemical biosensors [3][4][5], fluorescent biosensors [6], colorimetric biosensors [7,8], potentiometric biosensors [9,10], optical biosensors [11], and Raman spectroscopy-based platforms [12,13]. Compared with other detection methods, electrochemistry biosensing platforms provide a more facile, cost-effective and a highly sensitive detection method which enables the fast response-recovery times, monitoring different analytes, and a very low detection limit [14][15][16].…”

“…Biosensors have received tremendous attention as an alternative to the conventional analytical methods due to the unparalleled specificity, sensitivity, rapidity of analysis and the ability to provide a long-term monitoring and a wide range of detection capabilities, including glucose, blood oxygen level, antibodies, mycotoxins, heavy metals in drinking water, pesticides, nucleic acid and body motions pesticides [ 2 ]. A variety of approaches have been exploited, including electrochemical biosensors [ 3 – 5 ], fluorescent biosensors [ 6 ], colorimetric biosensors [ 7 , 8 ], potentiometric biosensors [ 9 , 10 ], optical biosensors [ 11 ], and Raman spectroscopy-based platforms [ 12 , 13 ]. Compared with other detection methods, electrochemistry biosensing platforms provide a more facile, cost-effective and a highly sensitive detection method which enables the fast response-recovery times, monitoring different analytes, and a very low detection limit [ 14 – 16 ].…”
