Biodegradable poly(D,L-lactide-co-glycolide) (PLGA) and bioactive hydroxyapatite (HAP) are selected for the formation of a multifunctional system with the specific core-shell structure to be applied as a carrier of a drug. As a result, both components of PLGA/HAp core-shells are able to capture one part of the drug. Polymeric shells consisting of small nanospheres up to 20 nm in size act as a matrix in which one part of the drug is dispersed. In the same time, ceramic cores are formed of rod-like hydroxyapatite particles at the surface of which another part of the drug is adsorbed onto the interface between the polymer and the ceramics. The content of the loaded drug, as well as the selected solvent/non-solvent system, have a crucial influence on the resulting PLGA/HAp morphology and, finally, unimodal distribution of core-shells is obtained. The redistribution of the drug between the organic and inorganic parts of the material is expected to provide an interesting contribution to the ...kinetics of the drug release resulting in non-typical two-step drug release.
