- Abstract
Silver nanoparticles were produced inside a poly( N-vinyl-2-pyrrolidone) hydrogel (PVP) by an innovative method based on the electrochemical reduction of Ag+ ions within the swollen PVP hydrogel. UV-visible spectroscopy showed the highest value of the absorbance intensity and the lowest values of the wavelength of the absorbance maximum and the full width at the half-maximum absorbance for the Ag/PVP nanocomposite obtained at 200 V during 4 min. Cyclic voltammetry results suggested an adequate entrapment of the silver nanoparticles. The mechanical properties under bioreactor conditions of the Ag/PVP nanocomposite suggested the possibility of wound dressing application. Silver release from Ag/PVP nanocomposites was confirmed under static conditions as well as by their antimicrobial activity against Staphylococcus aureus. POLYM.
