Abstract

The aim of this work was to prepare composite microspheres with high sphericity and narrow size distribution based on chitosan-copper complex and bioactive glass (bioglass). The influence of the bioactive glass content on the size and morphology of chitosan-copper complex microspheres was investigated. The electrohydrodynamic atomization process was used to produce highly spherical particles of narrow size distribution and with defined surface morphology. The addition of bioglass particles caused the surface changes, from smooth to wrinkled surface by increasing the bioglass quantity. The size of the obtained microspheres was estimated to be between 40 and 100 μm, depending on the bioglass content.
