From: Graphdiyne-modified TiO2 nanofibers with osteoinductive and enhanced photocatalytic antibacterial activities to prevent implant infection

Fig. 1

a Transmission electron microscopy image of TiO2/GDY (left, scale bar = 0.5 μm) (n = 3 separate materials) and illustration of the TiO2/GDY structure (right). b Raman spectra of TiO2/GDY. The main peaks of TiO2 are shown in the red box, and the magnified peaks of GDY are shown in blue. c Absorption curves and photos of rhodamine B degradation by TiO2 and TiO2/GDY photocatalysis under UV irradiation for different times (0, 15, 30, 45, and 60 min). d Trends in the absorbance peaks of the RhB curves at each UV exposure time point. e Areas under the absorption curves at each time point. f Electron spin resonance for •OH (below) and •O2− (above) generation after TiO2 (blue) and TiO2/GDY (red) were induced by UV. g Contact angle measurements of TiO2 and TiO2/GDY nanofibers. Source data of b–f are provided as a Source Data file.
