A. (a) Schematic illustration for the bifuctional GO-TCP scaffolds. b) Photograph of 3D printed pure β-TCP (left) and GO-TCP (right) scaffolds; microscopic images of pure c) β-TCP and d) GO-TCP scaffolds; (e) GO-TCP scaffolds show a distinct photothermal effect under 808 nm laser irradiation. Adapted with permission from [236]. B. (a) C3N4 sheets and the two-photon fluorescence spectra for the C3N4 sheets dispersed in water for red-light excitation. (b) Comparison of phosphate-buffered saline (PBS) and C3N4 sheets for the enhancement in repairing critical size cranial bone defect under red light in vivo: 3D μ-CT analysis of bone regeneration after 3 days or 4 weeks. Regenerated bone is indicated with a yellow color. Adapted with permission from [240].
