Application laser transfer of metal nanoparticles to bacterial biofilms

The method of application laser transfer of silver and copper nanoparticles for the first time has been shown to be effective against biofilms formed on a solid substrate. It has been experimentally confirmed that this effect is not associated with the influence of the laser itself. The proposed method allows one to increase the locality, availability, and efficiency of biofilm destruction due to the bactericidal effect of metal nanoparticles with a slight direct laser effect on the biofilm.
