Characterization of the wormhole mesoporous silica nanoparticles (W-MSN). (A) Scanning transmission electron micrograph (STEM). Images of CW-MSN Core with an average particle size size of 26 ± 2.3 d.nm. Particles were measured using Image J https://imagej.net/Downloads. (B) Dynamic light scattering (DLS) results indicated that the MSN solution was monodisperse with a recorded PDI of 0.08 At 24 h, CW-MSN core reached their largest size (34.2 ± 2.0 d. nm), and further increases in size were not observed at 48 h and 72 h. (C) Dynamic light scattering indicates the average size of the particle at 24 h is 33.07 d nm. (D) Chitosan conjugation of the W-MSN (CW-MSN) increased the size of the W-MSN cores to 39.2 ± 1.9 d. nm.
