Introduction: The objective of the present study was to improve the anti-inflammatory and antibacterial activities of mastic gum resin (MGR). MGR was loaded into a phospholipid nanocarrier with or without partially hydrolyzed ginsenoside, followed by dispersion into distilled water.
Method: The phospholipid nanocarrier dispersion showed significantly enhanced in-vitro release, porcine skin/ intestine permeation, and retention. When the ratio of the MGR versus partially hydrogenated ginsenoside reached 1:1 w/w in the nanocarrier composition, the in-vitro release increased 54.8-fold compared to the MGR powder suspended in the release media.
Results: Permeation of the nanocarrier dispersion through the porcine skin and intestine increased 160-fold and 42-fold, respectively, compared to permeation of the MGR powder suspension. Furthermore, the nanocarrier dispersion reduced NO production and iNOS mRNA expression in the LPS-stimulated RAW264.7 cells. MIC and MBC of the nanocarrier dispersion against P. gingivalis were 4.11 ± 1.17 and 8.22 ± 2.35 μg/mL, respectively.
Conclusion: In conclusion, the anti-inflammatory and antibacterial activities of MGR were remarkably enhanced when the MGR was loaded into the nanocarrier with partially hydrolyzed ginsenoside.

Micelles, liposomes, and solid lipid nanoparticles (SLNs) are promising drug delivery vehicles; however, poor aqueous stability requires post-processing drying methods for maintaining long-term stability. The objective of this study was to compare the potential of lipid-based micelles, liposomes, and SLNs for producing stable re-dispersible spray-dried powders with trehalose or a combination of trehalose and L-leucine. This study provides novel insights into the implementation of spray drying as a technique to enhance long-term stability for these lipid-based nanocarriers.

Understanding photodegradation of nanogels is critical for dynamic control of their properties and functionalities. We focus on nanogels formed by end-linking of four-arm polyethylene glycol precursors with photolabile groups and characterize dynamic heterogeneities in these systems during degradation. We use our recently developed dissipative particle dynamics framework that captures the controlled scission of bonds between the precursors and diffusion of degraded fragments at the mesoscale.

Zein-based nanoparticles (NPs) have attracted considerable attention as potential delivery systems for bioactive compounds. However, their application has been limited by poor stability and redispersibility. In this study, we addressed these challenges by fabricating zein nanocarriers using branching structural fructo-oligosaccharides (P-FOS) and sodium caseinate (NaCas) as costabilizers.
