Summary: Due to the destruction of the ozone layer, increased exposure to UV radiation negatively affects both skin diseases and wound healing. To address the limitations in safety of commercially available sunscreens, researchers developed a highly safe sunscreen using a silk fibroin composite with biocompatibility and blood coagulation activity. By improving the solubility of silk fibroin and incorporating tannic acid and zinc oxide nanoparticles, a multifunctional hydrogel sunscreen was created with UV blocking, hemostatic, antibacterial, and antioxidant effects.

Summary: This research focuses on the influence of the reduction process of TiO2 nanostructures on the surface properties of a bioinspired Ti modified implant. By optimizing the production of reduced TiO2 nanotubes (RNT) and comparing them with simple TiO2 nanotubes (NT), it was found that the presence of RNT on Ti allows for easy deposition of silk fibroin (SF) film. The hybrid film was then functionalized with ZnO nanoparticles to improve the antibacterial effect of the coating. Surface analysis confirmed that SF was effectively attached to the TiO2 nanotube surfaces. Evaluation of the modified Ti surface showed hydrophilic characteristics.
