Characterization of surface-functionalized MSNs.

Notes: (A) Scanning electron microscopy: MSNs were monodisperse, spherical, and evenly shaped. (B) Transmission electron microscopy: MSNs were mesoporous and approximately 100 nm in size. (C) ζ-Potential of synthesized MSNs by dynamic light-scattering measurements, showing the change in surface charge for the lipid and PEG surface-functionalized MSNs. (D) Representation of lipid and/or PEGylated surface-functionalized MSNs with sample coding.

Abbreviations: Lip, lipid; MSNs, mesoporous silica nanoparticles; PEG, polyethylene glycol.
