Nanotechnology is a branch of technology that manipulates the molecular structure of materials to alter their inherent properties and create new ones with revolutionary applications. This is the case with graphene, a modified carbon that is harder than steel, lighter than aluminum, and nearly transparent, and these nanoparticles are utilized in electronics, energy, healthcare, and defense. Nanotechnology is a hot topic in research and development around the world, and nanomaterials are already found in hundreds of items, including sunscreens, cosmetics, fabrics, and sports equipment. Drug delivery, biosensors, and other medicinal uses are all being developed with nanotechnology.
