Introductionto Nanomaterials (original) (raw)

Nanomaterials, defined as substances with at least one dimension under 100 nanometers, play a critical role in nanoscience and nanotechnology, offering unique optical, magnetic, and electrical properties. These materials, both natural and engineered, are increasingly found in various commercial products, from electronics to cosmetics. The historical journey of nanomaterials spans significant scientific advancements, beginning with Michael Faraday's synthesis of colloidal gold and continuing through the development of numerous nanostructured materials with diverse applications.
