Nanomaterials are materials that are characterized by their extremely small size, typically on the nanometer scale (1-100 nanometers). This small size gives nanomaterials unique properties and behaviors that are distinct from their bulk counterparts. Nanomaterials have a wide range of applications in various fields such as electronics, medicine, energy, and environmental remediation. Research in nanomaterials focuses on synthesizing, characterizing, and exploring the properties and potential applications of these materials at the nanoscale level. Some common types of nanomaterials include nanoparticles, nanotubes, nanowires, and nanocomposites. Overall, nanomaterials research is a rapidly growing and interdisciplinary field that has the potential to greatly impact future technological advancements.
