Auto-Cross-Linking Hydrogels of Hydrogen Peroxide-Oxidized Pectin and Gelatin for Applications in Controlled Drug Delivery

Figure 1

Swelling kinetics for different formulations of hydrogels incubated in PBS. All samples were prepared with HOP figures which are variations in gelatin concentration: (a) OP hydrogels with 20% gelatin, (b) OP hydrogels with 15% gelatin, and (c) OP hydrogels with 10% gelatin. The first number in the legend indicates the HOP composition, and the second number corresponds to the gelatin concentration, i.e., H4.10 is the hydrogel with 4% HOP and 10% gelatin.
