Figure 1 Schematics of an antimicrobial surface
Silicone elastomer based products like tube, hose, gaskets, fittings are widely used specially in the area like medical, pharmaceuticals, biotechnical, cell-culture treatment, and oncological applications. This fittings are used either in-vivo or in-vitro condition that are directly contact with physiological state.

The reason of using silicone elastomer based product more intensely in this arenas because silicone rubber is entirely bio-compatible, high heat resistance and chemical resistance, low leachability and good aesthetics as it is transparent. Inertness comes from its internal chemical structure. As this silicones are directly used in physiological condition industries are focused to developed anti-microbial silicones products. Anti-microbial activity describes as the destruction or inhibition of the growth and development of microorganisms and pathogenic microorganisms. Anti microbial products are inhibiting the growth of bacteria over the surface so that contagious infection is to be minimized.

This anti-microbial products that are equipped with an antimicrobial additive, consumers are benefitting in a number of ways. The antimicrobial protection infused into the product fights against product-damaging microbes that can quicken its deterioration. Stain and odor-causing microbes are also inhibited, and this helps to keep the product stay fresher and cleaner for longer. Importantly, the antimicrobial additive technology does not wash off or wear away, and will continually fight against potentially harmful bacteria that makes contact with the surface of the product.
Anti-microbial silicone have been used in many arenas not only in medical, pharmaceutical sectors but also in house hold application.

Above are some examples of antimicrobial silicone products. Other than that antimicrobial products are also used in prosthetic, body implantation, blood translation and other area to minimize the risk of generation of microbial activity with time.
