Abstract

Alpha-lipoic acid (ALA) is a naturally occurring antioxidant that has attracted considerable interest for its applications in nanobiotechnology, controlled drug delivery, and agricultural sciences. In the present study, a magnetic chitosan-coated liposomal nanocomposite incorporating ALA was synthesized and comprehensively characterized. Structural analyses demonstrated a spherical and well-dispersed morphology with an average crystallite size of 19.42 nm, as determined by X-ray diffraction. Elemental characterization confirmed the presence of Fe, C, O, and S, with iron accounting for 64% of the composition, while FT-IR analysis verified successful integration of the composite constituents through characteristic functional group interactions. The antioxidant properties of ALA are associated with its ability to suppress lipid peroxidation and reduce oxidative damage caused by reactive oxygen species. These effects are particularly relevant for plant systems, where oxidative balance directly influences growth, development, stress tolerance, and overall physiological performance. To enhance the stability, bioavailability, and targeted delivery of ALA, liposomal formulations were functionalized with magnetic iron oxide and chitosan, yielding a multifunctional nanocarrier platform. The developed ALA-conjugated nanocomposite exhibited favorable physicochemical properties, including improved stability, controlled morphology, and enhanced surface characteristics. Owing to the biocompatible nature of liposomal and chitosan-based systems, the synthesized material is expected to possess low toxicity while maintaining efficient delivery performance. This study highlights the potential of magnetic chitosan-coated liposomal nanoparticles as innovative carriers for ALA and provides a basis for future investigations into their biological activity, biocompatibility, and applications in plant-based and therapeutic delivery systems.
