made significant efforts that culminated in the discovery of various two-dimensional
materials (Figure 3.2) including transition metal oxides (TMOs), layered double hydro
xide (LDH), transition metal dichalcogenides (TMDs), hexagonal boron nitride (h-BN),
black phosphorus (BP), g-C3N4, graphene, and MXenes [9]. Recently discovered 2D
materials also demonstrated unique electronic and other physicochemical features, in
cluding high surface area, flexibility, excellent biocompatibility, durable interfacial con
nection with cells, proteins, biomolecules, and other bio-organisms. These materials have
been employed for numerous applications, including biomedical science. Hence, unique
features of 2D materials have immense potential for the development of bioelectronic
