“…Silver antimicrobial properties have been recognized since historic times (Klasen, 2000, Burrell, 2003, and the coating of medical devices with silver coatings (Ewald et al, 2006, Bosetti et al, 2002, Darouiche, 1999, Schierholz et al, 1998 or the addition of silver nanoparticles (Chen et al, 2006, Kwok et al, 2007, Rai et al, 2009) into the material's surface might be a good method to prevent device-associated infections by physical routes instead of the chemical routes mentioned above. Silver exhibits a rather broad-spectrum antimicrobial activity in vitro by binding both to microbial DNA, preventing bacterial replication, and to the sulfhydryl groups of the metabolic enzymes of the bacterial electron transport chain, causing their inactivation (Darouiche, 1999).…”
