摘要：
Colloidal stability of core-shell nanoparticles consisted of silver core and chitosan/dextran sulfate multilayer shell in NaCl and CaCl2 solutions was investigated. The critical concentration of coagulation and the Hamaker constant were calculated depending on the number of bilayers in the shell on the nanoparticle surface. The colloidal stability of the core-shell nanoparticles significantly increases with the shell growth.
