The main environmental concern is the amount of silver involved. Some believe it to affect living cells. There is also concern that the silver could seep into the sewer systems and affect the purification process of waste water.
Nano silver refers to silver particles that are extremely small, typically less than 100 nanometers in size. Colloidal silver is a suspension of silver particles in a liquid, which may include nano silver particles. In general, colloidal silver can contain a range of different sized particles, while nano silver specifically refers to very small particles.
Nanocontainers are tiny structures or vessels at the nanoscale that can encapsulate or carry substances such as drugs, chemicals, or biomolecules. These nanocontainers can protect their contents from degradation, target specific locations, and release their cargo in a controlled manner, making them useful in drug delivery, imaging, and sensing applications.
It is rare, It is pretty, it doesn't rust and most importantly silver is widely used in nano technology and super-computer production because silver is the best conductor of any known metal. There is also cultural phenomenon to desire silver for jewelry and coins. As population grows, desire for silver grows to keep up with population. LATELY SILVER PRICES HAVE BEEN GROWING RAPIDLY AND DEMAND HAS INCREASED DUE TO THE GLOBAL, INTERNATIONAL CAMPAIGN "CRASH JPMorgan - BUY SILVER!"
Molecular technology involves manipulating, analyzing, and designing molecules to create new materials, drugs, or devices at the molecular level. Nanotechnology involves manipulating and creating structures on the nanoscale to develop new materials, devices, or systems with unique properties and functions. Both fields have applications in various industries such as healthcare, electronics, and materials science.
No such thing, because when you zoom in down to the nano scale gold is not gold anymore as its properties change at the nano scale.
Silver nano technology does not seem to be available in any Samsung products sold in the US. It does seem to be widely available, however, in the UK, Australia and Singapore.
Nano Technology
Nano Technology is the manipulation of matter on an atomic and molecular scale. The study of Nano technology is a sort of new technology that no one knows what will really come out of the measurements.

It is a fairly new technology.
the latest technology in field of electronics is the Nano technology.The Nano technology is going to be a revolution to the world.The world is going to be NANO.The nano technology has spread its net all over many fields.

Concerns have been raised, however, over the use and marketing of washing machines using the silver nano technology. The German branch of Friends of the Earth, Bund für Umwelt und Naturschutz Deutschland (BUND), has warned consumers not to buy a new type of washing machine that uses silver nanoparticles. BUND criticized the product, noting that considerable amounts of silver could enter sewage plants and seriously trouble the biological purification process of waste water. In addition, silver nanoparticles were claimed to have a toxic effect on different kinds of living cells.[7][8] Samsung countered that only an accumulated amount of 0.05 grams of silver is released per machine, per year, while the released silver-ions quickly bind to non-nano-sized structures in the water.[9] Korea Times quotes Hwang Ee-taek, a co-author of the paper stating that firms like Samsung and LG Electronics started from the idea that silver-nanoparticles kill bacteria and they actually do. But scientists are still unsure of whether they are safe for humans. This field of research is still at a very rudimentary stage.[10] However in another news, Hong Kong University researchers believe that silver nano may hold a solution to one of China's worst health concerns, the spread of hepatitis B, which can cause liver cancer and liver failure. The silver nano-particles have another advantage since it is unlikely that HBV can become resistant to silver nano-particles because the interaction is determined by the physicochemical properties of the tiny particles. The study is still in the laboratory stage and any findings it may generate are still three to five years away from clinic use.
