Poly(L-lactide-co-glycolide) (PLG) was modified through the adsorption of collagen to improve the behaviour of fibroblasts and osteoblasts. As reference materials cell-resistant polystyrene (PS) and cell-conductive tissue-culture polystyrene (TCPS) were also evaluated. The physicochemical surface properties of the materials were studied by X-ray photoelectron spectroscopy (XPS), atomic force microscopy...
