摘要

Lipid-based nanotherapeutics (LNTs) represent a notable advancement in drug delivery systems, primarily due to their ability to encapsulate and efficiently transport therapeutic agents. To ensure the stability, efficacy, and safety of these nanoscale structures, a comprehensive array of analytical techniques is required for their characterization. This review article delineates the principal methods employed in the characterization of lipid-based nanotherapeutics. It emphasizes structural characterization techniques such as dynamic light scattering (DLS), transmission electron microscopy (TEM), and atomic force microscopy (AFM) for the evaluation of size, morphology, and surface characteristics. Furthermore, spectroscopic methods, including nuclear magnetic resonance (NMR) and Fourier-transform infrared spectroscopy (FTIR), are examined for their roles in analyzing lipid composition, encapsulation efficiency, and drug release kinetics. The article also highlights the importance of techniques such as differential scanning calorimetry (DSC) and X-ray diffraction (XRD) in assessing lipid bilayer transitions and crystallinity. A comprehensive understanding of these characterization methods is crucial for optimizing lipid-based nanotherapeutics to achieve enhanced therapeutic outcomes in various biomedical applications.
