Nanotechnology in sanitization

Germ killing nano light gun
To sanitize work place, kitchen or a toilet normal UV light emitting gadgets or ozonator is used. The UV light has been proven to reduce up to 99.9% of the bacteria and up to 90% of dust mite eggs. It also kills microscopic germs like flea eggs, lice and mold.
Nanotechnology comes to help in this fled of sanitation. A nanotechnology based germ killing gun has been developed by Hammacher Schlemmer & Company, Inc., N.Y. The hand held germ eliminating light is of cell phone-sized disinfectant unit using multi-wavelength UV-A, UV-B, and UV-C light to eliminate 99.9% of E.coli, staphylococcus, salmonella, and germs that cause the flu and the common cold. The light uses the same UV technology found in hospitals to sterilize surgical instruments and to disinfect workplace, keyboards or telephones, as well as items in the home that sustain germ vitality such as tooth brushes and cutting boards. Without using toxic chemicals, the light disinfects surfaces in 10 seconds as it is held 6 to10 mm away from the contaminated surface. The internal timer signals when sterilization is complete, while the automatic shut-off feature ensures safety. The unit fits easily in a shirt pocket or briefcase for convenient travel. The bulb in the unit is 5,000-hour rated and is run by two AAA batteries. But it seems the item is not in supply from the company.
The Oreck Halo UV-C germ killing light
This gadget utilizes UV-C light to help remove bacteria and viruses. It can be used not only on the carpet, but in areas with hardwood or linoleum to get it sanitized and to swipe the kitchen clean. This germ eliminating upright vacuum unit comes with a disposable HEPA filter bag which captures 99.97% of all particles down to the size of 0.3 microns. It has a 35 watt UV-C light unit (as used in hospital sterilization equipment) mounted on the base which will additionally serve to eliminate 99.9% of potentially harmful, otherwise invisible things as against standard vacuums which cannot destroy dust mites, mould, flea eggs and even viruses and bacteria. The UV-C vacuum cleaner comes with a powerful 6 ¼ amp motor, a detachable hose for stair carpets and with the embedded UV-C bulb rated at 8000 hours. It proves as an invaluable tool to fight not only against dust but also germs and pet related bugs.
