Preparation and Properties of Bimetallic Chitosan Spherical Microgels.

ABSTRACT: The aim of this work was to prepare bimetallic chitosan microgels with high sphericity and investigate the influences of metal-ion type and content on the size, morphology, swelling, degradation and biological properties of microgels. Amino and hydroxyl groups of chitosan (deacetylation degree, DD, of 83.2% and 96.9%) served as ligands in the Cu²⁺-Zn²⁺/chitosan complexes with various contents of cupric and zinc ions. The electrohydrodynamic atomization process was used to produce highly spherical microgels with a narrow size distribution and with surface morphology changing from wrinkled to smooth by increasing Cu²⁺ ions' quantity in bimetallic systems for both used chitosans. The size of the bimetallic chitosan particles was estimated to be between
