Characterization of Cur-AgNPs and shear-thinning properties of the composite GG/Cur-AgNPs self-healing hydrogel. (a) UV–Vis spectrum of Cur-AgNPs. (b) TEM image of Cur-AgNPs. (c) the average diameter of Cur-AgNPs is 18.24 ± 4.20 nm (n = 75) from TEM. (d) Viscosity of the hydrogel composite as a function of shear rate. The hydrogel shows shear thinning which is a favorable property for injectability. e, The concentration of silver ions (Ag+) released by ‘high’ (1000 μg/mL) and ‘standard’ (500 μg/mL) concentrations of Cur-AgNPs, and for the same concentrations of Cur-AgNPs encapsulated in the GG hydrogel.
