Summary: Mesoporous silica nanoparticles (MSNs) are ideal nanocarriers with high specific surface area, adjustable pore size, and good biocompatibility. In this study, MSNs with different particle sizes were prepared and used as carriers for the pesticide spirotetramat.

Summary: The adsorption of polymers on the surface of mesoporous silica nanoparticles allows for versatile adhesion between hydrogels or biological tissues. However, when the number of nanoparticles deposited exceeds a critical threshold, thick multilayers form at the interface and decrease the adhesion strength. To overcome this limitation, spherical aggregates were prepared by spray drying, resulting in stronger cohesion between nanoparticles. The adhesion energy with these supraballs was significantly enhanced compared to nanoparticles, and corrugated interfaces stabilized by supraballs contributed to the largest adhesion enhancement.

Summary: DSC and PFGSE NMR were used to characterize water in hydrogels of ETTMP and PEGDA. DSC quantified freezable and nonfreezable water, while PFGSE NMR measured water diffusion coefficients. Both techniques showed decreasing ratios of bound/nonfreezable water mass per polymer mass with increasing polymer content. Swelling studies determined the equilibrium water content (EWC) of different compositions, showing that fully cured ETTMP/PEGDA hydrogels at specific polymer mass fractions were at EWC.

Summary: Mesoporous silica nanoparticles (MSNs) have great potential as a drug delivery platform, but the complex synthesis and surface functionalization protocols impede clinical translation. Surface functionalization with PEGylation to improve blood circulation time often reduces drug loading levels. In this study, sequential adsorptive drug loading and adsorptive PEGylation were performed to minimize drug desorption. The solubility of PEG in both water and apolar solvents enabled the use of a solvent with low drug solubility for PEGylation. Analysis of serum protein adsorption and PEG conformation confirmed the effectiveness of the approach. The stable PEG coating supports the fast translation of this drug delivery platform to the clinic.

Summary: An efficient nanoparticulate drug carrier for chemotherapy through intravenous administration needs to have a long circulation time in blood, good penetrability into tumors, and efficient uptake by cancer cells. However, the development of nanomedicine in delivering nanoparticles to solid tumors is hindered by the lack of simple, reproducible, cheap, and predictive methods for identifying promising nanoparticle formulations. This study performed a preliminary evaluation of a simple screening method based on nanoparticle uptake in vitro, which showed promising results correlated with literature results in small animal models.
