Recent progress in the field of multicomponent bioactive nanostructured films

Abstract

Multicomponent bioactive nanostructured films (MuBiNaFs) with an excellent combination of chemical, mechanical, tribological, and biological properties were developed and deposited by sputtering of composite targets produced via the self-propagating high-temperature synthesis method. Reviewed substrate materials included Ti-, Ni-, and Co-based alloys, insoluble polymers, and deimmunized donor's bones. Our results showed that the MuBiNaF deposition can be effectively combined with either a bulk material modification to improve its mechanical properties, or a surface modification to control surface roughness and blind porosity. Among other promising applications, the fabrication of hybrid materials incorporated with stem cells or medicine is mentioned.
