  • X-ray photoelectron spectroscopy (XPS) verified DA surface localization.
  • Quartz crystal microbalance with dissipation monitoring (QCM-D) assessed CSNP swelling and DA-CSNP interaction.

    • Main Results:

    • Successful formulation of DA-loaded CSNPs was achieved.
    • FTIR and XPS confirmed the successful loading and surface localization of DA within the CSNPs.
    • QCM-D analysis demonstrated rapid DA-CSNP interaction, leading to a stable nanostructured system.
    • QCM-D also provided insights into the swelling behavior of the CSNPs.

    Conclusions:

    • DA-loaded CSNPs represent a promising nanostructured system for potential therapeutic applications in Parkinson's disease.
    • The characterized CSNPs exhibit stability and efficient DA interaction, suitable for drug delivery systems.
    • Further studies are warranted to explore the in vivo efficacy of these DA-loaded CSNPs for Parkinson's disease treatment.
