Fabrication of strontium-incorporated protein supramolecular nanofilm on titanium substrates for promoting osteogenesis

The inherent biological inertness of Ti substrates is a general challenge in orthopedic and dental clinical application. In this study, the strontium-containing phase change lysozyme coating was prepared on titanium via a supramolecular self-assembly method for accelerating osseointegration. Successful preparation of the Sr-incorporated lysozyme nanofilm onto the Ti substrate (Ti-Ly-Sr) was proved by tests of scanning electron microscopy (SEM),...
