Nanosilver coatings

The application of nanosilver in medicine is particularly an important issue. The method of production of nanosilver-coated polymers, which are used as plastic catheters, has been developed. A coating with silver nanoparticies acts as an antibacterial and disinfectant. The in vitro tests confirmed growth inhibition in the bacterial layer which was sustained for 72 h (Roe et al., 2008). In patent... 

A new approach comes from advance in nanotechnology that offer an opportunity for the discovery of novel compounds with antibiofihn activity. One such example is nanosilver crystals, which show potent antimicrobial activity and have been used to coat catheters (100). Furthermore the use of nanofabrication surface techniques can change surface properties such as charge, wetability, and topography, in addition to the ability to add functional activities. The precise control of surface composition and chemical functionality, along with novel methods such as microwave synthesis, discussed in this chapter, promote our abihty to attach nanoparticles to a wide range of surfaces and can offer important new tools to combat bacterial biofllm persistence.
