Nanotechnology involves controlling and modifying matter at the atomic and molecular scale, between 1 to 100 nanometers. It deals with developing and changing materials and devices at the nanoscale. Nanotechnology is already making today's products lighter, stronger, faster, smaller and more durable. It involves simulations like molecular dynamics to study molecular behavior and interactions at the atomic level. Current applications include wound dressings, water filtration, paints and coatings. Future uses may include advanced computers, solar cells, and tissue regeneration.
