Introduction to Nanomaterials 2025-26

Nanomaterials are substances with structures at the nanometer scale (typically under 100 nm), exhibiting unique properties due to their size, such as increased reactivity, strength, and quantum effects. They come in various forms like nanoparticles, nanotubes, and nanowires, and are produced through top-down or bottom-up methods. Widely used in fields like electronics, medicine, energy, and environmental science, nanomaterials offer great potential but also raise concerns about safety and environmental impact.
