Abstract
In this study we examined a novel composite consisting of collagen and elastin in order to create a biodegradable matrix to serve as a biomimetic surface for cell attachment. Confocal microscopy images of modified zones reveal formation of surface fringe patterns with orientation direction alongside the area of interaction. Outside the crater rim a wave-like topography pattern is observed. Structured, on a nanometer scale, surface array is employed for cell-culture experiments for testing cell's responses to substrate morphology. Mice fibroblasts migration was monitored after 3Â days cultivation period using FESEM. We found that fibroblasts cells tend to migrate and adhere along the laser modified zones. The performed study proved that the immobilized collagen based biofilms suite as a template for successful fibroblasts cell guidance and orientation. Fs laser induced morphological modification of biomimetic materials exhibit direct control over fibroblasts behaviour due to induced change in their wettability state.
