2 , the intrinsic fluorescence intensity of SRP showed an increasing trend when the ultrasound time was from 0 to 20 min.
With the further increase of cross-linking time, the water-holding capacity of SRP showed a decreasing trend, which might be due to the disruption of the stabilizing structure formed, resulting in the weakening of water-holding capacity [ 17 ].
