2D Materials for Bioelectronics

2D materials have recently drawn interest because for their potential use in bioelectronics. It poses unique electronic, mechanical, and chemical properties. These materials have high surface-to-volume ratios, are ultrathin (just a few atoms or molecules thick), and are well suited for interacting with biological systems.

Graphene, a single layer of carbon atoms which arranged in a hexagonal structure, Graphene is one of the most studied 2D materials for bioelectronics. It poses high electrical conductivity, more surface area, and biocompatibility, making it a desirable choice for various biomedical applications, such as biosensors, drug delivery, and tissue engineering.

Other 2D materials like transition metal dichalcogenides (TMDs) such as molybdenum disulfide (MoS2) and tungsten diselenide (WSe2), have a similar hexagonal lattice structure to graphene. But with a greater range of electrical and optical properties.

Moreover, black phosphorus (BP) is establishing itself as a feasible 2D material for bioelectronics, due to its adjustable bandgap and biocompatibility. BP-based devices have been demonstrated for biosensing, bioimaging, and drug delivery applications.

Over all, 2D materials have become popular for employing in bioelectronics due to their unique characteristics, and active research is exploring their potential for a wide range of biomedical applications.
