Hong Kong testing anti-bacterial nano-coating in subways
Hong Kong is now testing an anti-bacterial silver-titanium dioxide nanoparticle coating on surfaces in its subway cars, says ABC News. Expect to see the same in London's tube in the near future.
With news of powerful flu strains like the avian flu and hand-transmissible diseases such as colds, public transportation operators in Asia and Europe have considered using a new disinfectant in their undergrounds. Many surfaces that people touch every day in the tube, as the London subway system is called, also carry thousands of bacteria and germs, according to experts.
"Public transportation is a very common way, we know, of how diseases … spread," says Ben Mascall, spokesman with MTR Corp., which operates the railway in Hong Kong and has bid for two new rail franchises in the United Kingdom.
"Some viruses can stay on a surface for 24 hours," says Dr. John Trainer, at the University of Rochester in New York.
Hong Kong is among the first cities to test one of the latest anti-flu products, nano silver-titianium dioxide coating, or NSTDC. It is applied to all surfaces inside a subway car. The preliminary tests conducted in Hong Kong show that the disinfectant reduces the amount of bacteria by 60 percent, says Mascall.
Ironically, titanium dioxide nanoparticles are also found in sunscreens, which the ETC Group wants banned pending further studies of their potential toxicity.

December 25th, 2006 at 8:04 pmOnce upon a time, there was an ugly girl. She was short and dumpy, had one leg a bit shorter than the other, and her eyebrows met in the middle. The ugly girl gutted fish for a living, so her hands smelt funny and her dress was covered in scales. She had no mother or brother, no father, sister, or any friends. She lived in a ramshackle house on the outskirts of the village, and she never complained.
March 5th, 2009 at 2:25 amOne by one, the village girls married the local lads, and up the path to the church they’d prance, smiling all the way. At the weddings, the ugly girl always stood at the back of the church, smelling slightly of brine. The village women gossiped about the ugly girl. They wondered what she did with the money she earns. The ugly girl never bought a new frock, never made repairs to the house, and never drank in the village tavern.
Now, it so happened that outside the village, in a great damp swamp, lived an old basket-maker who was famed for the quality of his work. One day the old basket-maker heard a knock on his door. When he opened it, the ugly girl stood there. In her hand, she held six gold coins. The Wicker Husband.
Throughout history, silver has been recognized as one of the most efficient germicides known. While an antibiotic can kill as many as a half-dozen different kinds of disease organisms, silver is known to kill some 650 species of bacteria or viruses simply by coming into contact with them. Particle size has been the only limiting factor to silver’s effectiveness. Now through nano-technology, a rapidly growing science of producing and utilizing particles that measure in nanometers (1 billionth of a meter), silver can be used efficiently as an antimicrobial in medicines, filters, clothing and personal hygiene products. Some appliances may not be worth looking into getting quick loans to get your hands on them. A growing number of home appliances, such as dishwashers, washing machines and dryers, have a dose of a potentially toxic particle, called nano silver, also known as silver nano, a patented form of colloidal silver or silver particles that are spread out on the molecular level. You couldn’t get enough quick loans to get the microscope you’d need to see them. The Environmental Protection Agency has yet to publish testing results, but it is believed that nano-silver has toxic effects. Silver poisoning is known to be toxic. The chelation therapy you need to reverse it costs more than a few quick loans worth.
