Abstract: Nanoparticles of aluminum oxide partially coated with silver were obtained by the radiation-chemical method in size 50 and 80 nm, and the coating area was 2-3% and 16-40%, respectively. The stability of the suspension before irradiation using different stabilizers was studied. The reason for the color change of suspensions after sonication is determined. The antibacterial activity of the composite nanopowder was investigated on wine yeast.
Keywords: nanopowders, nanoparticles, nanosecond electron beam, silver-coated alumina, antibacterial properties.
