Fig. 6. Schematic of the dual function of TiO2/GDY in orthopedic implant infection.

Fig. 6

On the one hand, electrons transferred from UV (365 nm)-irradiated TiO2 nanofibers to GDY resulted in more reactive oxygen species generation for sterilization. On the other hand, osteoblasts tended to adhere to the nanofibers due to the great biocompatibility of GDY. The blue dashed box exhibits the free electron generation and transfer in TiO2/GDY. “e−” in the blue dashed box represents negative electron, while “h+” represents positive hole.
