Abstract
Branched star-like dextran-polyacrylamide copolymers in nonionic and ionic forms are used as matrices for the fabrication of silver nanoparticles. It is demonstrated that due to the features of their molecular structure providing a high local concentration of functional groups, branched polymers stabilize silver nanoparticles more efficiently as compared with their linear analogs. Stable silver colloids are obtained in a branched anionic matrix, meanwhile a linear matrix does not stabilize a nanosystem.
