Synthesis and application of graphene-based sensors in biology: a review

A cooperation tale of biomolecules and nanomaterials in nanoscale chiral sensing and separation

“…102 Graphene was considered a desirable candidate for fabricating high-performance sensors due to its satisfactory electrical conductivity, biocompatibility, and ultrahigh surface area. [103][104][105][106][107] The electrical detection of enantiomers could be achieved by transferring the inhibition effect of methamidophos on acetylcholinesterase to graphene. An efficient electrochemical sensor based on Fe 3 O 4 @Au@Ag@ CuxO NPs was fabricated for the chiral recognition of D-AAs.…”

Potential of nanobiosensor in sustainable agriculture: the state-of-art

“…Graphene is highly biocompatible and contains oxygenated functional groups, which allow chemical functionalization to form metal composites. Due to these distinctive features, graphene-based biosensors are considered as promising candidates ( Verma et al., 2022 ). Among the uses of nanobiosensors, sensing soil quality, plant pathogens, phytohormones, pesticides, and heavy metals are of utmost importance ( Ali et al., 2021 ).…”

An electrochemical sensor for flubendiamide insecticide analysis based on chitosan/reduced graphene oxide

“…Graphene has been found to have excellent properties for different fields including electronic gadgets, 1 nanocomposites, 2 energy storage such as ultra-capacitors, [3][4][5] and batteries, 6 fuel cells, [7][8][9][10][11] solar cells, [12][13][14] and biotechnologies. [15][16][17][18][19] However, due to the high cost and difficulty of producing graphene, several efforts have been made to develop efficient and affordable processes to produce and use graphene derivatives, such as graphene oxide (GO). GO is highly stable in aqueous colloids because of the presence of oxygen functional groups, promoting the repulsive electrostatic interactions at the edges.…”
