Published on: February 25, 2021

Main Results:

  • SLNs exhibited small particle size (<100 nm), ellipsoidal shape, and low polydispersity.
  • (1)H NMR confirmed solid core structure and PEGylated surface.
  • Interactions, including a stearyl alcohol-Brij 78 eutectic, were observed, potentially enhancing drug loading but posing a stability issue due to a low melting point.

Conclusions:

  • Nanotemplate engineered SLNs possess promising characteristics for drug delivery.
  • Formulation modifications are necessary to overcome identified physiological stability challenges.
  • Optimized SLNs are expected to be effective drug delivery systems.
