A laser ablation method is suggested to synthesize a dispersion of silver nanoparticles to create a bactericidal coating of biodegradable suture material from poly(glycolide-co-lactide) using a bulk target immersed in a liquid. The laser ablation method with nanosecond excitation by a Nd:YAG laser (1064 nm, 7 ns) is used to obtain silver nanoparticles with mean diameter of 27 nm in ethanol. Nanoparticle concentrations up to 12 mass% were obtained on the polymer surfaces by multiple impregnation.
