Figure Lengend Snippet: Preparation and characterization of Lip-Exo/Pae. (A) Fluorescence inverted microscope pictures of liposome-exosome fusion (liposomes in red, exosomes in green, Lip-Exo/Pae in yellow). (B) Schematic diagram of liposome and exosome fusion. (C) Appearance of Lip-Exo/Pae solution. (D) Tyndall effect of Lip-Exo/Pae colloidal solution. (E) TEM Image of Lip-Exo/Pae. TEM Image of Lip-Exo/Pae. Scale bars represent 200 nm. (F) Particle size distribution map of Lip-Exo/Pae. (G) Zeta potential and PDI of Lip-Exo/Pae. (H) In vitro dialysis release curves of each formulation group. (I) The release curves were fitted to each formulation group using the Weibull mathematical model. (J) ABTS clearance results for each group of formulations at varying concentrations. (K) The scavenging results of hydroxyl radicals by different concentrations of each formulation group. (L) Blood compatibility test results of Lip-Exo/Pae. (M) Cell viability after 24-h incubation of HT22 cells with varying concentrations of Lip-Exo/Pae.
