The paper describes the effect of different thermal treatments on the morphology and
binding properties of particles prepared using a transacylation reaction between two
biocompatible polymers, namely propylene glycol alginate and human serum albumin.
Compared to control alginate gel microspheres, albumin–alginate covalent network offers a
better resistance to the microspheres towards freezing, lyophilization and sterilization. The
binding properties for methylene blue were not altered by the treatments. Moreover, stability …
