FT Research on Glucose Adsorption and Detection Using Edge-Passivated Graphene

There is a growing need to create non-enzymatic glucose sensors with excellent sensing accuracy and biocompatibility.Because of their distinct electronic characteristics, two-dimensional graphene-like nanomaterials and functionalized graphene now offer the best solutions available for the next generation of extremely sensitive glucose sensors.Consequently, we used DFT to study the glucose molecule's interaction with hydrogen-and fluorine-passivated graphene nanoflakes.In light of this, studies were conducted on the electronic, structural, and adsorption energy properties of glucose molecules adsorbed on these sheets.The findings suggest that the glucose molecule binds poorly with both sheets, exhibiting a low adsorption energy.These sheets cannot be utilised as electronic or work function-based sensors because the energy gap and work function values are not sensibly varied.
