Latest Research Progress on Titanium in the Biomedical Field

1.Choline chloride-modified chitosan coating: Studies have shown that at a concentration of 0.1-0.2g/100mL, the choline chloride (ChCl)-modified chitosan (CS) coating exhibits optimal adhesion and corrosion resistance on titanium surfaces, along with high hydrophilicity and the ability to inhibit Staphylococcus aureus colonization. The coating significantly reduces corrosion current density and promotes calcium-phosphate deposition, indicating excellent biocompatibility and biological activity, making it suitable for bone implants.

2.Nanostructured titanium alloys: Nanostructured titanium alloys prepared through severe plastic deformation technology exhibit significantly enhanced strength, fatigue performance, and biocompatibility in medical implants, making them suitable for the design and manufacturing of miniaturized implant devices such as those in dentistry and orthopedics, and have been successfully applied in innovative medical equipment like vascular clip devices.

3.Perovskite solar cells: Although primarily focused on solar cells, Professor Zhongmin Zhou's team's research on in-situ dynamic regulation of buried interface strain in stable perovskite solar cells may indirectly affect the energy supply and stability of biomedical devices.

These research advances demonstrate the extensive potential of titanium and its alloys in the biomedical field, particularly in improving the biocompatibility, corrosion resistance, and mechanical properties of implants.
