Abstract

HAp-nanoparticle-coated biodegradable polymer microspheres loaded with magnetic Fe₃O₄ particles can be successfully prepared by evaporating volatile oil (dichloromethane) from HAp-nanoparticle-stabilized oil droplets containing biodegradable polymer and Fe₃O₄ particles without any molecular surfactants or polymeric stabilizers. In this study it was found that the hydrophobic surface modification for the Fe ₃O₄ particles was a key factor to prepare stable HAp-nanoparticle-stabilized oil droplets (and HAp-nanoparticle-coated polymer microspheres) loaded with magnetic Fe₃O₄ particles.
