The present work aimed to investigation of influence molecular weight of chitosan, method of silver nanoparticles producing and immobilization, amount of cross-linking agent on antibacterial activity. Silver was incorporated in the matrix in two ways: 1 пїЅ by the recovery of silver ions from AgNO3 solution; 2 ? by addition to hydrogel the silver nanoparticles, obtained previously by microbiological synthesis. The molecular weight of chitosan shows strong influence on internal structure of matrices and on release ...
