Various industries are integrating nanotechnology to enhance product performance and create new functionalities. In the automotive sector, nanotechnology is used to develop lighter and stronger materials, such as carbon-fiber composites, which improve fuel efficiency and safety. In the textile industry, nanotechnology is used to create fabrics that are stain-resistant, water-repellent, and antimicrobial. The cosmetics industry also benefits from nanotechnology through the incorporation of nanoparticles in sunscreens and anti-aging products, which provide better protection and skin penetration.
