1% iodophor loaded microspheres of PLGA (Poly[DL-Lactide-co-Glycolide]) were prepared by solvent evaporation method and were applied to the cows on dry period for evaluating it's preventive effects on intramammary infections. The morphology of the microspheres were evaluated using scanning electron microscopy and their releasing patterns were investigated. On investigating idophor releasing patterns of the microsphere, burst releasing pattern was detected until 2 days after in vitro incubation and sustained releasing was observed until 4 weeks.
