Fig. 3. Hierarchical multi-chambered mesoporous nanoparticles with tunable opening and chamber distribution.
a–c Structural models, TEM images, and d the corresponding distribution histograms of the body length of the multi-chambered mesoporous nanoparticles with tunable openings; a single-chamber, b dual-chambers, c tri-chambers. e–g Structural models and TEM images of the dual-chambered nanoparticles with tunable chamber distance. h The relative changes of center distance and the diameter of the second chamber. Error bars represent standard deviation. Source data are provided as a Source Data file.
