One nanomaterial that is having an early impact in health care product is nano-silver. Silver has been used for the treatment of medical ailments for over 100 years due to its natural antibacterial and antifungal properties. The nano silver particles typically measure 25nm. They have extremely large relatively surface area, increasing their contact with bacteria or fungi, and vastly improving its bactericidal and fungicidal effectiveness. The nano silver when in contact with bacteria and fungus will adversely affect cellular metabolism and inhibit cell growth. The nano silver suppresses respiration, basal metabolism of electron transfer system, and transport of substrate in the microbial cell membrane. The nano silver inhibits multiplication and growth of those bacteria and fungi which cause infection, odor, itchiness and sores. Nano Silver can be applied to range of other healthcare products such as dressings for burns, scald, skin donor and recipient sites; acne and cavity wounds; and female hygiene products – panty liners, sanitary towels and pants.
