Abstract: The work is aimed at solving the problems of spraying disinfectant liquids for the sanitization of people, premises,
vehicles and open spaces. Currently, there are ways to solve the problems associated with ultrasonic atomization of liquids. The
presented specialized ultrasound devices provide the ability to spray and use disinfectant fluids depending on the presence of silver
nanoparticles.
