From: Visible-light-assisted multimechanism design for one-step engineering tough hydrogels in seconds
a The proposed schematic illustration for preparing tough hydrogels. b Fluorescent image of propidium iodide and fluorescein diacetate co-staining cells in the solution after irradiation. c Confocal fluorescent images of cells after 24 and 48 h incubation in hydrogels. d THVMD hydrogels under daylight and UV light irradiation. Letters of “G, E and L”: Hydrogels with different M–N networks of Tb3+, Eu3+, and Al3+, respectively; Letters of “N, W and U”: Hydrogels with different P–N networks of PEG, PAAm and PNIPAM, respectively. The scale bar is 1 cm.
