Iranian researchers have succeeded in producing antibacterial carpet using nano technology which can be used in schools, hospitals and other health centers.

According to Iran Nanotechnology Initiative Council, the average amount of bacteria found in a homeowner’s carpet is 200,000 organisms per square inch. This amount is 4,000 times more than that found on an average homeowner’s toilet seat! So the use of disinfectants which leads to reduced activity of these organisms, can be important.

Silver particles are stabilized easily in nano-dimension which leads to formation more stable colloids. The most noticeable advantages of silver nanoparticles are in biomedicine. It could be mentioned that in nano-dimension, antibacterial effect of silver increases significantly, so that they are able to destroy over 650 bacterial species.

These nanoparticles have significant antifungal activities against some ringworms. Silver nanoparticles disrupt fungal structure and cause significant damage to fungal cells. It is also demonstrated the cytoprotective activity of silver nanoparticles (5-20 nm) toward HIV-1 infected cells.

The modified electrochemical properties of silver nanoparticles can also offer faster response times and lower detection limits in nano-scale sensors. In the case of odor-resistant carpet, the textile industry recognizes that silver nanoparticles offer distinct properties that combat bacterial growth and reduce body odor.
