Silver nanoparticles were obtained by picosecond laser ablation in water at 1064 nm, using focusing geometry to design the particles size. The position of the target surface with respect to the focal point strongly influences the NPs size: above and in the focus it is up to 20 nm and below focus LT = 150 nm. Generated particles have a spherical shape. The solutions were further employed on human cells and the tests showed a deteriorating effect on DNA.
