Isolation and physicochemical characterization of CLDENs. A Schematic diagram of the separation process of CLDENs. B TEM analysis of CLDENs. Scale bar = 100 nm. C DLS was used to analyze the particle size distribution of CLDENs. D A nanoflow analyzer picked up the CLDENs particle size. E Analysis of CLDENs’ zeta surface charge. F,G Particle size changes of CLDENs in enzyme (F) and surfactant-containing (G) environments. H Stability of CLDENs in different pH environments. Particle size changes of CLDENs in pH = 6.92 (a), pH = 13.58 (b) and pH = 1.83 (c) environments. TEM imagines of CLDENs in pH = 6.92 (d), pH = 13.58 (e) and pH = 1.83 (f) environments. Scale bar = 200 nm. The white triangle marked the two fused vesicles
