Nanotechnology has been studied since the nineteenth century. Since Nobel Laureate Richard P. Feynman introduced the term "nanotechnology" in his well-known 1959 speech "There's Plenty of Room at the Bottom, several groundbreaking advancements in the field of nanotechnology have occurred. At the nanoscale, nanotechnology createda variety of materials. Nanoparticles are a broad category of materials that comprise particulate compounds with a minimum diameter of 100 nm. These materials can be 0D, 1D, 2D, or 3D depending on the overall form.
