The present study describes the coating of porous scaffolds (based on 45S5 bioactive glass and produced by the foam replica method) with zein, a storage protein derived from corn. As bioactive scaffolds show microcracks on the surface, the mechanical performance is very weak. By applying a polymer layer, these cracks can be filled and bridged, which leads to enhanced fracture strength and toughness. Therefore, bioactive glass-based scaffolds are immersed in a zein solution. After evaporation of the solvent, a thin polymer film of ~10 μm remains on the surface. The microstructure and morphology were investigated by scanning electron microscopy (SEM). Furthermore, the influence of the coating on the bioactive behavior of the scaffolds was tested by immersion in simulated body fluid (SBF). The formation of hydroxyapatite was analyzed by SEM and Fourier Transform Infrared Spectrometry (FTIR). By applying a zein coating, the compressive strength was increased by factor 5.
