Where is nanotechnology used today?
Nanotechnology is used in many commercial products and processes. Nanomaterials are used to add strength to composite materials used to make lightweight tennis rackets, baseball bats, and bicycles. Nanostructured catalysts are used to make chemical manufacturing processes more efficient, saving energy and reducing the waste products. A few pharmaceutical products have been reformulated with nanosized particles to improve their absorption and make them easier to administer. Opticians apply nanocoatings to eyeglasses to make them easier to keep clean and harder to scratch. Nanomaterials are applied as coatings on fabrics to make clothing stain resistant and easy to care for. Several companies make nanostructured products using space-saving insulators that are useful when size and weight is at a premium—for example, when insulating long pipelines in remote places, or trying to reduce heating losses in a leaky old house. Nanoceramics are used in some dental implants, or to fill holes in bo
