**5. Conclusions**

1. The Ag-cotton nanocomposites synthesized via MVS has a pronounced antimicrobial activity against some Gram-positive and Gram-negative bacteria.

2. Antibacterial properties of medical gauze bandage containing AgNPs significantly increase when exposed to laser radiation. The effect of enhancing the antibacterial properties of the nanocomposite apparently associated with the effect of localized plasmon resonance of AgNPs.

3. TEM data indicate that the particle size distribution is narrow and monomodal with average particle size of 1.75 nm. EDA shows that interplanar distances correspond to metallic nanoparticles. XPS and EXAFS demonstrate that Ag atoms in Ag/bandage system is Ag0, the oxidized silver is in the form of Ag-Ag-O groups.
