Abstract
The silver and copper nanoparticles in water and ethanol extracts of some plants were synthesized by the method of “green” chemistry. The synthesized nanoparticles are studied by the methods of a spectophotometery, dynamic light scattering and their stability is studied. The possibility of reduction of the sizes of nanoparticles is shown by the method of an ultrasonic dispersion. The synthesized nanoparticles are used as carriers of new antitubercular drugs.
