Silver nanoparticles attach to the surface of the cell membrane and disturb such properties as permeability and respiration. It is reasonable to assume that the binding of the particles to the microorganisms depends on the surface area available for interaction. Smaller particles having the large surface area available for the interaction will give a greater bactericidal effect than larger particles According toINSO 11070, this fiber shows a remarkableantibacterial activit.
The polymeric materials can easily be colonized by bacteria or fungi,frequently causing severe infections and transmitting disease. The prevention of microbial colonization of polymeric surfaces can be achieved by adding active antimicrobial agent like silver nanoparticles into the polymers. Polyesteris a category of polymers that contain the ester functional group in their main chain. Polyester fibers have high tenacity, low water absorption and minimal shrinkage in comparison with other industrial fibers. This material is used very widely in clothing. Silver ions and compounds are highly toxic for a wide range of bacteria and they show very low toxicity for human cells, so that, the use of silver in different forms has been a common method for antibacterial protection.
