Different letters in each column (a, b, c) represents a significant difference between treatments (P < 0.05) and data are shown as mean ± standard deviation (n = 3)

L-0: empty nanoliposomes; L-F1: nanoliposome loaded with < 5 kDa peptides; L-F2: nanoliposome loaded with 5–10 kDa peptide; L-F3: nanoliposomes loaded with crude peptide (2 mg/mL)
