Development and characterization of microencapsulated microspheres.
Pharmaceutical research 11 (11), pp. 1568-74.
A process for the coating of polymer microspheres with the same or different polymers and the characterization of these particles is described. Coated microspheres were manufactured from degradable and non-degradable polymers. Several physicochemical methods were used to establish that the particles were fully coated. Polarized light microscopy revealed strong birefringence of coated microspheres ...
