Abstract:
In the last decades, research on various biomedical topics focused on multifunctional coatings containing biodegradable and biocompatible materials, targeting cells activity and enhancing the bio-response . Enhancing cellular response can be performed by embedding various active factors, such as nanoparticles, proteins. Within this context, this work is focused on embedding 2 active factors(HA and lactoferrin (LF)) within synthetic biodegradable Poly(ethylene glycol)-block-poly(ε-caprolactone) methylether (PEG-block-PCL Me) for the preparation of new biodegradable composite layers by matrix assisted pulsed laser evaporation (MAPLE) method. The resulting features were studied by AFM and SEM. FTIR data demonstrates that the functional groups in the MAPLE-deposited films remain intact for the individual compounds and that LF was not affected by the solvents used for copolymer. The bio-functionality of the coatings has as a final aim the modulated response of osteoblast cells (i.e. adhesion, mineralization).
