(A) TEM image of n(SOD&CAT) capsules. (B) The hydrodynamic size and zeta potential of n(SOD&CAT) capsules. (C and D) The changes of hydrodynamic size and zeta potential of n(SOD) and n(CAT) capsules stored at room temperature within 5 days. (E and F) The CD spectra of native SOD, CAT, n(SOD) and n(CAT). Data were expressed as mean value ± SD of triplicate experiments.
