Abstract:

The main idea of MagReSSTiR project is to develop new types of 3D biomimetic, magnetic responsive scaffolds for bone repair and regeneration. The proposed concept will allow stimulated bone regeneration under remote controlled external magnetic field using magnetic responsive scaffolds with osteoconductive, osteoinductive and osteogenic characteristics similar to autogeneous bone grafts. Advanced laser micro- and nanofabrication technologies will be involved in building the biomimetic 3D architecture of the scaffolds. The magnetic field will stimulate the natural processes that regenerate and restore bone tissue to its functional state. A gradient deposition of nanocomposites employing hydroxyapatite, polymers, collagen and growth factors will help us to find the optimum ratio for which the osteogenesis will rise considerably. We also aim to get insight into the mechanisms of magnetic stimulated bone regeneration via in situ, in real time monitorization of the scaffolds/cells during the action of magnetic stimuli.

Abstract:

The ultrashort pulsed lasers are intensively used for fundamental research and technological developments in the field in material processing and characterization. In a "bottom-up" approach, under laser irradiation below the ablation threshold, periodical structures with sub-wavelength periodicity can be self-organized providing an efficient method for nano-texturing of large areas, for application such as fabrication of hydrophobic surfaces, bio-mimetic surfaces, surfaces with modified tribologic properties, colour marking of metals. However, some characteristics of the laser induced periodical surface structures (LIPSS), like poor contrast, bifurcations and truncations, can limit the functionality of the patterned surfaces. In order to find paths to control such patterns, more efforts have to be focused to the investigation of the mechanism formation of the nanostructures. The femtosecond lasers offer the unique possibility to simultaneously process and characterise the irradiated surfaces at time scale comparable with the dynamic of the nanostructures formations. The project proposes to develop time-resolved techniques for investigation of the mechanisms of the nanostructures formation, giving information about the build-up time of different types of nanostructures. An ultrafast holographic interferometry approach will be used for investigation of the time evolution of the irradiated surface at time scales of hundreds of picosecond with sub-picosecond time resolution.
