A new enzyme-free biosensor based on nitrogen-doped graphene with high sensing performance for electrochemical detection of glucose at biological pH value

Nickel oxide decorated MoS2nanosheet-based non-enzymatic sensor for the selective detection of glucose

“…On the other hand, layered two dimensional (2D) transition metal dichalcogenides (TMDs) such as molybdenum disulphide (MoS 2 ), [37][38][39][40] tungsten disulphide (WS 2 ) and graphene 41 have been used to fabricate electrochemical sensors. 42 As an important candidate, MoS 2 consisting of a S-Mo-S bonded trilayered structure 43,44 (with a band gap in the range of 1.2 to 1.8 eV) has shown high catalytic activity, surface area and electrical conductivity.…”

Biosensors—Recent Advances and Future Challenges in Electrode Materials

“…Functional doping of graphene with heteroatoms such as N, S, B, P, and F is an excellent pathway to enhance electron transfer processes [63]. Among them, nitrogen-doped graphene (NG) offers better electrochemical activity owing to the positive charge density in carbon atoms adjacent to N dopants, enhancing the conductivity of the material [67]. A multilayer biosensor containing GOx, nitrogen-doped graphene, chitosan, and poly(styrene sulfonate) was constructed layer-by-layer [68].…”

A Review of the Construction of Nano-Hybrids for Electrochemical Biosensing of Glucose

“…within graphene and carbon nanotubes could enhance the electrocatalytic properties of these carbon materials. Mansour et al recently investigated the glucose detection performance of microwave treated N-functionalized doped graphene [42]. Chen et al prepared nitrogen- and sulfur-based dual-doped graphene via a two-step solvothermal method for improving the electrocatalytic sensing performance towards glucose [43].…”
