Abstract

Poly(D,L-lactide-co-glycolide) (PLGA) with encapsulated hydrophobic magnetite (Fe3O4) nanoparticles or hydroxyapatite (HAp) nanoparticles were prepared by the w/o/w emulsion technique. The weight ratios of nanoparticles (Fe3O4 or HAp) to PLGA and polymer molecular weight were varied in the oil phase and the properties of the composite nanoparticles were studied. The final weight percent of nanoparticles in the spherical PLGA particles varied from ~ 5 to 60 wt%. Hydrodynamic diameters of the composite nanoparticles as measured by dynamic light scattering (DLS) were found to decrease with decreasing polymer molecular weight and were independent of nanoparticle loading. Particle sizes measured from TEM were smaller by almost a factor of two vs. those obtained from DLS. The zeta potentials of the particles were about − 23 mV, independent of polymer molecular weight and nanoparticle loading within statistical significance. In vitro cytotoxicity tests show a high level of cytocompatibility suggesting satisfactory biocompatibility for biomedical applications.
