Nano Water Purification

Developed at Stanford University for developing countries, this new water filter system uses nano sized silver wires and copper tubes, dipped in cotton, to block bacteria 80,000 times faster than any other filter.

Possible Solar Fabric - Silicon Nanowire

This silicon nanowire technology could allow for the creation of weaved fabrics that can absorb solar energy. These technology is still in the early phases of development at Cal. Tech. University.

Nano Tech: Spray On Liquid Glass

It makes your clothing invincible to the elements. SiO2 Ultra-Thin layering spray coats clothing with a thin protective layer that repels dirt, heat, UV radiation, and infections.

The image shows the SiO2 coating on a filament of a microfibre, illustrating the 100 nanometer thick protective layer.

"... the nano-scale glass coating bonds to the surface because of the quantum forces involved. According to the manufacturers, liquid glass has a long-lasting antibacterial effect because microbes landing on the surface cannot divide or replicate easily."


"A year-long trial of the spray in a Lancashire hospital also produced "very promising" results for a range of applications including coatings for equipment, medical implants, catheters, sutures and bandages. The war graves association in the UK is investigating using the spray to treat stone monuments and grave stones, since trials have shown the coating protects against weathering and graffiti. Trials in Turkey are testing the product on monuments such as the Ataturk Mausoleum in Ankara."
