Abstract

In this work it was evaluated the bactericidal effect of silver and silver-gold nanoparticles coated with silicon dioxide on Xanthomonas fragariae. Nanoparticles were synthesized by combining laser ablation and chemical synthesis techniques. Irradiating the samples at the same wavelength where nanoparticles exhibit its maximum absorbance is possible to photo induce the bactericidal effect by detonating the surface plasmon resonance. The results showed that the minimum bactericidal concentration (MBC) of silver nanoparticles was 16 μM (referred to [AgNO3]) and for silver-gold nanoparticles were 32 μM (referred to [AgNO3-HAuCl4]) at 60 minutes of irradiation.
