Fig. 7From: In situ synthesis of silver nanoparticles on the surface of PDMS with high antibacterial activity and biosafety toward an implantable medical devicePhotographic images of an AgNP grown PDMS film at 36 h after inoculation of S. aureus on the surface. a Control PDMS was prepared without the AgNP growing reaction. From b to d, AgNP-grown PDMS films subjected to one, two, or three rounds of reactions, respectively. Inset in each figure is an enlarged image of the figureBack to article page
