Abstract:<\/p>\n

 <\/p>\n

Structural organization and antimicrobial properties of nanocomposites based on pectin, polyethyleneimine and Ag nanoparticles, which formed by the chemical and thermochemical reduction methods from polyelectrolyte\u2013metal complexes pectin\u2013Ag<\/em>+<\/em>\u2013polyethyleneimine have been investigated. Such type of nanocomposites with Ag nanoparticles incorporated into polymer matrix is obtained due to the chemical reduction of Ag<\/em>+<\/em>\u00a0ions by NaBH<\/em>4<\/em>\u00a0in the polyelectrolyte complex. The appearance of the silver metallic phase is observed in full extent while BH<\/em>4<\/em>\u2013 <\/em>: Ag<\/em>+<\/em>\u00a0molar ratio is equal to 2.0. It is defined that thermochemical reduction of Ag<\/em>+<\/em>\u00a0ions in polyelectrolyte\u2013metal complexes bulk (while films are heated to the temperature around 100 \u00b0<\/em>\u0421<\/em> and more) also results in formation of silver-containing nanocomposites. The antimicrobial investigation of the elaborated nanocomposites has been revealed. They possess a high antimicrobial activity against S. aureus and E. coli strains.<\/em><\/p>\n
