What is Nanotechnology?
Nanotechnology is the manipulation of matter on an atomic, molecular, and supramolecular scale. The field involves creating materials, devices, and systems with new properties and functions due to their small size. Nanotechnology has the potential to revolutionize various sectors, from medicine to electronics to energy production.
How do Nanotechnology Products Work?
Nanotechnology products are designed at a scale of 1 to 100 nanometers. At this scale, materials exhibit unique physical, chemical, and biological properties, which can be exploited to create products with enhanced features. For instance,
nanomaterials can be engineered to be stronger, lighter, or more chemically reactive than their larger-scale counterparts.
Nanoparticles in medicine for drug delivery and imaging.
Carbon nanotubes for stronger, lighter materials in construction and manufacturing.
Nanocoatings for improved durability and functionality in textiles and surfaces.
