Transformative Bioactive Wear Resistant Ti3Au:N and Ti3Au:O Coatings for Medical Implants and Devices

Advanced Healthcare Materials, EarlyView.
Coatings of titanium‐gold are grown in nitrogen and oxygen environments via magnetron sputtering to simultaneously enhance their biotribological and antibacterial properties. The coatings are highly crystalline with superhard scratch‐resistant surfaces and wear rates 20 times lower than the bare Ti‐6Al‐4V substrate.

SiO2‐CaOCME/Poly(Tetrahydrofuran)/Poly(Caprolactone) 3D‐Printed Scaffolds Drive Human‐Bone Marrow Stromal Cell Osteogenic Differentiation

Advanced Healthcare Materials, EarlyView.
3D printed hybrid scaffolds combining bioactive silica–calcium chemistry with elastic polymers guide human bone stem cells to form bone. The scaffolds support cell survival, organization, and invasion while releasing osteogenic ions. Together, architecture and composition drive bone‐specific gene expression, extracellular matrix organization, and ...
