FIELD: chemistry.
SUBSTANCE: invention refers to nanotechnologies and can be used in medicine, pharmaceutics and cosmetology. Platinum metal nanoparticles are produced in a water-based 7 transparent liquid at damaging platinum metal or alloy target 6 by cavitation observed by laser light 2 delivery in the form of focused laser light 2 pulses on copper vapour 1 at pulse energy 1-5 mJ and pulse length 20 ns, pulse repetition frequency 10-15 kHz and power density 5.7 GWt/cm2, through a transparent bottom of the tray 5 to the target 6 placed into the tray 5 with the water-based 7 transparent liquid.
EFFECT: invention enables producing pure uncontaminated nanoparticles in the form of flakes of no more than 200 nm in size.
