Face amino-rich GQDs- ε- PL is prepared by changing the addition quantum of ε- PL. also, GQDs- ε-PL@4-arm cut- BA/ QCS hydrogels( GQDs- ε-PL@Gel) are synthesized through dynamic imine bondscross-linking. The sol can transfigure snappily to gel and the gelation time can be controlled by conforming the specific graveness of the input raw accoutrements to water. FT- IR and thermogravimetric analyses indicate the successful conflation of GQDs- ε- PL and GQDs- ε-PL@Gel.
The microstructure observation reveals that GQDs- ε- PL has a distance- suchlike structure with an average size of 65 nm, while GQDs- ε-PL@Gel has a pervious network structure. Both GQDs- ε- PL and GQDs- ε-PL@Gel have good luminescence stability, photothermal and cytocompatibility, and display better antibacterial effect against Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa through chemical and photothermal synergistic sterilization. More importantly, GQDs- ε-PL@Gel can constantly tone- heal after being damaged, which is more salutary to give an effective crack check terrain for injuries and to be used as crack dressings.
