Summary: The release of drugs or vaccine molecules from carriers is limited by diffusion and/or carrier dissolution and/or erosion. With decreasing carrier size, the release becomes kinetically limited. Nanocarriers often have structural heterogeneity, where molecule absorption is affected by energetic heterogeneity. A kinetic model is proposed, and the predicted kinetics can be fitted by Weibull or Korsmeyer-Peppas expressions.

Summary: Novel multi-responsive drug delivery vehicles (CDs/PNVCL@HMSNs) were prepared by grafting amino-terminated poly (N-vinyl caprolactam) (PNVCL-NH2) and amino-rich carbon dots (CDs) on the surface of aldehyde-functionalized HMSNs (HMSNs-CHO) via Schiff base reaction. The drug release behaviors of CDs/PNVCL@HMSNs-DOX showed temperature and pH responsiveness due to the poly (N-vinyl caprolactam) (PNVCL) and Schiff base bond. The multi-responsive CDs/PNVCL@HMSNs are intriguing drug carriers, which combine drug delivery and NO release in one.

Summary: Mesoporous silica nanoparticles (MSNs) are utilized as carriers in drug and gene delivery research for biomedical applications due to their high surface area, consistent particle size, and minimal toxicity. By incorporating disulfide (SS) bonds into the walls of MSNs, a dual pathway for drug release is provided. Various characterization methods are employed to study the effect of embedding disulfide bonds into MSNs. The study demonstrates that MSN-SS is a promising nanocarrier for controlled-release drug delivery with efficient pH-responsive drug release behavior.

Summary: A method was developed to synthesize hollow mesoporous nanoparticles with controllable size and shell thickness for drug-delivery applications. Monodispersed hollow mesoporous organosilica (HMOS) and hollow mesoporous silica (HMS) nanoparticles were successfully prepared using soft and hard templating methods. The hollow size of HMOS can be tuned by changing the size of the hard templates, and the shell thicknesses of HMOS and HMS can be adjusted by changing the amount of precursor used.

Summary: Bubble-like manganese silicate nanoparticles have attracted much attention due to their wide range of applications, but there is still debate over their formation mechanisms. In this study, we revisit the formation of these nanoparticles and demonstrate a solid-to-hollow conversion process. An intermediate solid MnxOy(CO3)mSiz is formed during the hydrothermal reaction, and its thermal decomposition leads to the transformation from solid to hollow structure. Finally, bubble-like manganese silicate nanoparticles are formed. These findings are expected to provide insights for designing other hollow metal silicate nanoparticles.
