a Solubilization of ellagic acid (EA) by nanosponges (having different cross-linking density), fabricated via different methods and β-CD. Statistical data analysis from the one-way ANOVA was followed by Bonferroni's Multiple Comparison Test: (***p < 0.0001). c indicates p < 0.001 vs. NS1, e indicates p < 0.001 vs. NS3, d indicates p < 0.0001 vs. NS2, f indicates p < 0.05 vs. NS4. b Encapsulation efficiency of all the batches of nanosponges, ellagic acid loaded nanosponge fabricated via melt method (EANS1 and EANS 2) and ellagic acid loaded nanosponges fabricated via microwave synthesis (EANS3 and EANS4)
