Physiochemical characterization of the PNM. (A) The average size of the PNM by DLS and TEM. (B) The long-term stability of the PNM in size and PDI. (C) The zeta potential of the PNM in water, PBS and plasma. (D) The UV absorption spectrum of PF, Flav and PNM. (E) The encapsulation efficiency and loading efficiency of the PNM. (F) The release profiles of PF in 10 mmol/L GSH and PBS. Data are shown as the mean ± SD (n = 3).
