Characterization of the mmLbL-INS microcapsules. (A–C) SEM images and DLS results of LbL-INS microcapsules with (A) one layer, (B) two layers, and (C) four layers. (1) SEM images, (2) high-magnification SEM image, (3) dynamic light scattering (DLS) results. (D) Zeta potentials of multiple LbL-INS microcapsules with different layers. (E) Relationship between the initial INS concentration and INS loading content in the LbL-INS microcapsules. (F) INS release behavior of multiple LbL-INS microcapsules in pH 6.5 solution. (G) SEM images, DLS results, and the image of mmLbL-INS microcapsules.
