Table 1.

Effect of different concentrations of enzyme input on size, zeta potential, polydispersity index (PDI), drug entrapment and drug loading in chitosan-PEGylated nanoparticles (CS-LO-PEG NPs). The results are presented as mean ± SE. Superscript letters on the values indicates significant differences between the data in the column (p < 0.05).
