Silver nanoparticles were synthesized with the laser-assisted wet chemical approach at room temperature. The effect of light exposure on the silver nanoparticles' spatial parameters shaping the localized surface plasmon resonance has been evaluated. The optical, structural and morphological characterizations of the Ag nanostructures were conducted with UV-VIS-NIR spectrophotometry, DLS and TEM techniques. The ability of the light-modified Ag nanostructures for energy conversion under the influence of 445 and 880 nm laser radiation is estimated. We have found that the most efficient heat generation can be achieved using triangular Ag nanostructures under the NIR irradiation (880 nm). The temperature effect on the Ag nanostructures' antibacterial properties has been evaluated against the population. The prospects of triangular Ag nanostructures' application on modern endodontics for the rapid nano-laser disinfection of the root canal system of the human tooth have been demonstrated.
