Nano-drug delivery systems (NDDS) serve as a promising platform in modern medicine, facilitating the targeted delivery of drugs due to their versatile size, structure, and composition. However, the current industrial production of NDDS relies on cumbersome batch processes that are costly, difficult to scale, and lack adequate control. This study focuses on enhancing industrial-scale production through the development and testing of a continuous top-down production line, utilizing scalable Microfluidizer® technology for solvent-free preparation of lipid-based nanoparticles.

This study aimed to evaluate the potential of Hydrophobic Ion Pairing combined with Solid Lipid Nanoparticles (SLN) and Nanostructured Lipid Carriers (NLC) to improve peptide transport across the intestinal border using Caco-2 cell monolayers (enterocyte-like model) and Caco-2/HT29-MTX co-cultured monolayers (mucin-secreting model).
This study showed that hydrophobic ion pairing enabled high encapsulation efficiency of peptide in SLN and NLC. The lipid-based nanocarriers were highly internalized by Caco-2 cell monolayers and were able to cross the mucus barrier (Caco-2/HT29-MTX cell model). However, the peptide intestinal transport was limited by an extensive release from the carriers.
