From poly lactic acid and polyvinyl alcohol coated scaffolds gentamicin was released within 20h and 50h, respectively. The conventional methods of supplying a patient with pharmacologic active substances suffer from being very poorly selective, so that damage can occurs to the healthy tissues and organs, different from the intended target.Author: Dagnija Loca, Janis Locs, Kristine Salma, Juris Gulbis, Ilze Salma, Liga Berzina-Cimdina

Natural variation in bone density occurs in the axial direction of long bones, displaying a gradient in porous structure from cortical bone to cancellous bone . This suggests bone implants made of porous gradient biomaterials that can mimic the properties of natural bone with a porosity-graded structure, may perform significantly better in bone regeneration applications.Author: Naghmeh Abbasi, Stephen Hamlet, Robert M. Love, Nam-Trung Nguyen

The particle size distribution of the crushed hydroxyapatite powder and as synthesized porous scaffold are shown in Fig. 5. The hydroxyapatite powder presents a mono-modal distribution with an average particle size of 6.5 μm, whereas the crushed hydroxyapatite scaffolds present a blunt bimodal distribution with two maxima at ∼6.5 and ∼61 μm.Author: Garima Tripathi, Bikramjit Basu
