Silver (Ag) has been incorporated in several items that require to be free from bacteria such as socks, underwear, running shirts, and so on. This is to resolve how many individuals fear germs, thus, having it to keep one healthy. However, several scientists and environment analysts warn users and manufacturers that silver may impose health and environment risks, though still uncertain what these effects would be.

Silver is certainly a powerful antimicrobial property. It is broken down into tiny pieces, better known as nanoparticle, to ensure efficacy. Because of that, these particles are being used in almost everything! However, new researches state that these nanoparticles are harmful. In one of the experiments, it has been seen that Chlamydomonas reinhardtii, a type of algae, reacted on the nanosilver. Its rates of photosynthesis and levels of ATP lowered after exposure. However, after a while, the algae executed a defensive response and cleansed itself from all the adverse effects the nanosilver has imposed. It also had fought the damage it has caused on the algae.

With such occurrence, several professionals from the field of science are questioning its efficacy. They are also concerned of probably negative effects it could bring in the near future. Bacteria has a capability to fight off a remedy, especially if not administered well, therefore it could also happen to a nanosilver.

Nano-sized particles are not required to be labeled on an item. Because of that, consumers are not aware if they are using an item which has silver. Now, the US Environmental Protection Agency (EPA) requires companies to register their products if it has nanosilver in it.
