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.

金属纳米粒子激光转移到细菌生物膜上的应用

应用激光转移银和铜纳米颗粒的方法首次被证明对形成在固体基材上的生物膜有效。实验证实，这种效应与激光本身的影响无关。由于金属纳米粒子的杀菌作用和对生物膜的轻微直接激光作用，所提出的方法允许人们增加生物膜破坏的局部性、可用性和效率。
