A The preparation process of in-situ photosynthetic system and photocrosslinking mechanism. B Absorption spectra of LAP (blue), C. pyre (green) and upconversion emission spectra of NaCeF4:Yb,Tm,Zr (pink) upon excitation at 980 nm with a power density of 1.0 W/cm2. C Photographs of NIR photocuring HCU covered over by chicken tissue with 10 mm thickness. D Pseudocolor SEM image of C. pyre (green) and UCNPs (yellow) within the HCU. Scale bar, 10 μm. E Adhesion of HCU with surfaces of various substrates. F Adhesion mechanism of the HCU gel. G The degradation process of HCU in the PBS. Independent experiments were performed (n = 3) for (D) with similar results. Source data are provided as a Source Data file.
