Student designer creates a nano dress that prevents colds

Fashion designers and fiber scientists at Cornell have designed a garment that can prevent colds and flu and never needs washing, and another that destroys harmful gases and protects the wearer from smog and air pollution.

The two-toned gold dress and metallic denim jacket contain cotton fabrics coated with nanoparticles that give them functional qualities never before seen in the fashion world.

Dipping the positively charged cotton into the negatively charged silver nanoparticle solution resulted in the particles clinging to the cotton fibers.  Silver possesses natural antibacterial qualities that are strengthened at the nanoscale, thus giving the dress the ability to deactivate many harmful bacteria and viruses.

One drawback may be the garments’ price: one square yard of nano-treated cotton would cost about $10,000.
