Nanoparticles for self-cleaning surfaces

Self-cleaning fabrics could revolutionize the sport apparel industry. Scientists of the U.S. Air Force have created t-shirts and underwear that can be worn hygienically for weeks without washing. This is done by attaching nanoparticles to clothing fibers using microwaves. Then, chemicals that can repel water, oil and bacteria are directly bound to the nanoparticles. These two elements combine to create a protective coating on the fibers of the material. This coating both kills bacteria, and forces liquids to bead and run off. This technology was originally developed for U.S. military to protect soldiers from biological weapons and to avoid casualties from bacterial infections due to wearing of underwear for several weeks.
