What does nanotechnology mean? Well it involves understanding and working with materials on a level of size where they are billionths of a meter in size. At this size certain materials have very important qualities and can easily penetrate into other materials at a molecular or atomic level.
First let's look at silver this metal has been used by many civilizations for centuries as a method of treating wounds and purifying water. Many cultures in our past including the Greeks and Romans have historical evidence of using silver to help treat wounds and infections. There is even a reference to King Cyrus of Persia in V BC who only drank water stored in silver containers. Many books including ancient Hindu religious books refer to dirty water being cleaned by placing heated silver into it for a short period of time. Burns were also treated with a silver solution and sometimes food was treated with silver to kill bacteria. Pioneers in America were known to put a silver coin, a dollar back then, into milk to preserve it longer before it went bad. Doctors began experimenting with medical uses silver and found various other areas other than wounds where it helped. Ulcers and fistulas that resisted other treatments were often cured quickly by using an application of silver water even ones that had been there for a few years. It was realized that silver not only had an ability to kill bacteria but also on a molecular level penetrated cells and aided regeneration of tissue. In 1920 the US government Food and Drug Administration endorsed the use of silver water in medicine and purification.
Samsung has always been at the forefront of new developments in many areas of research and development and has since the 1990s been looking at nanotechnology. Before even thinking about applying it to household appliances the company has for years been using it to advance telecommunications and semiconductors working with the Korean Governments own nanotechnology program.
The introduction of silver nanotechnology used in household appliances, was to introduce air conditioners, washing machines and refrigerators. Air conditioning with the Silver Nano Health System has been designed to kill all bacteria passing air through the air filter system as Silver Nano coated. It was a supply of clean sterilized germ-free from outside and also played during the return of 'indoor air was carried out to ensure that no bacteriaalready in the room would be killed. The washing machines have also had the nano-silver treatment, as could also be used to kill bacteria on clothing and linens. During the washing process silver nanos are released and mix with clothes that are killed for tissues at the molecular level all the bacteria that appears or after washing. They are estimated to be killing bacteria on clothing for up to 30 days after washing effect. Hospitals reported this as a great machineWay to deal with their mountains of laundry, which was really clean and germ-free deal. The refrigerator was having a coating of nano silver is growing in all its internal surfaces, bacteria or molds can not get a chance on it "means. It will be in a safer environment in the refrigerator as a result of these surfaces were previously a source of germs and possibly food poisoning.
