“…[203] Another magnetic material NiFe 2 O 4 not only possesses an intrinsic magnetic property but also enjoys the merits of spinel oxides, such as multiple oxidation states, less toxicity, capacitive nature and good biocompatibility. [177,204,205] Specifically, the metal ions act as electron acceptors to promote the biofilm formation, enhance the electron transfer efficiency and reduce the internal resistance. [177] Also, the continuous inter-conversion of cations with multiple states benefits the electron accumulation and bio-electrochemical performance.…”

site). The relationship is demonstrated in depth between the physicochemical properties of the anode surface/interface/bulk (porosity, surface area, hydrophilicity, partical size, charge, roughness, etc.) and the bioelectrochemical performances (electron transfer, electrolyte diffusion, capacitance, toxicity, start-up time, current, power density, voltage, etc.). An outlook for future work is also proposed.

“…Among the other 2D materials, MXene exhibited some special properties such as hydrophilicity, high specific surface area and good adsorption phenomena [ 23 ]. Due to the peculiar properties of MXenes, they have been used in various applications which include supercapacitors [ 24 ], batteries [ 25 ], microbial fuel cells [ 26 ], photocatalysis [ 27 ] and sensors [ 19 ]. Recently, MXene based electrochemical sensors had been reported for the sensing of glucose [ 28 ], ascorbic acid (AA), dopamine (DA) and uric acid (UA) [ 29 ], L-cysteine [ 30 ] and superoxide anions from human liver cancer cell lines (HepG2) [ 31 ].…”

Flavin adenine dinucleotide (FAD) is a coenzyme and acts as a redox cofactor in metabolic process. Owing to such problems as poor electron transfer properties, unfavorable adsorption, and lack of stability on rigid electrodes, the bio-electrochemical applications of FAD have been limited. Herein, a novel fabrication method was developed for the immobilization process using 2D MXene (Ti3C2Tx), which enhanced the redox property of FAD and improved the electro-catalytic reduction of hydrogen peroxide (H2O2) in neutral medium. The FAD-immobilized Ti3C2Tx electrode (FAD/Ti3C2Tx) was studied by UV-Visible and Raman spectroscopies, which confirmed the successful adsorption of FAD on the Ti3C2Tx surface. The surface morphology and the elemental composition of Ti3C2Tx were investigated by high resolution transmission electron microscopy and the energy dispersive X-ray analysis. The redox property of the FAD/Ti3C2Tx modified glassy carbon electrode (FAD/Ti3C2Tx/GCE) was highly dependent on pH and exhibited a stable redox peak at −0.455 V in neutral medium. Higher amounts of FAD molecules were loaded onto the 2D MXene (Ti3C2Tx)-modified electrode, which was two times higher than the values in the reported work, and the surface coverage (ᴦFAD) was 0.8 × 10−10 mol/cm2. The FAD/Ti3C2Tx modified sensor showed the electrocatalytic reduction of H2O2 at −0.47 V, which was 130 mV lower than the bare electrode. The FAD/Ti3C2Tx/GCE sensor showed a linear detection of H2O2 from 5 nM to 2 µM. The optimization of FAD deposition, amount of Ti3C2Tx loading, effect of pH and the interference study with common biochemicals such as glucose, lactose, dopamine (DA), potassium chloride (KCl), ascorbic acid (AA), amino acids, uric acid (UA), oxalic acid (OA), sodium chloride (NaCl) and acetaminophen (PA) have been carried out. The FAD/Ti3C2Tx/GCE showed high selectivity and reproducibility. Finally, the FAD/Ti3C2Tx modified electrode was successfully applied to detect H2O2 in ovarian cancer cell lines.
