The remarkable versatility of graphene, a single layer of carbon atoms arranged in a hexagonal lattice, has positioned it as a cornerstone material for next-generation technologies across diverse scientific and engineering disciplines. Its unique electronic, optical, and mechanical properties arise from its fundamental atomic structure and bonding. The ability to precisely engineer these properties through nanostructuring and functionalization has opened up unprecedented avenues for innovation. One of the most significant advancements lies in the tailoring of graphene nanostructures to unlock specific functionalities for advanced devices. By meticulously controlling parameters such as size, shape, and doping, researchers can engineer graphene's electronic, optical, and mechanical characteristics. This fine-tuning is crucial for developing applications in areas like highly sensitive biosensing, efficient energy storage solutions, and advanced optoelectronic devices [1].
