Nanomedicine Characterization Techniques

Abstract

Nanomedicine has emerged as a revolutionary approach in the diagnosis, prevention, and treatment of various diseases. Its unique physicochemical properties, such as high surface area-to-volume ratio, tunable surface chemistry, and size-dependent behavior, enable targeted drug delivery and enhanced therapeutic efficacy. Accurate characterization of nanomedicines is critical for understanding their biological interactions, stability, safety, and efficacy. This review comprehensively summarizes current nanomedicine characterization techniques, including physicochemical, morphological, structural, and biological methods. Techniques such as dynamic light scattering (DLS), transmission electron microscopy (TEM), atomic force microscopy (AFM), zeta potential analysis, X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), nuclear magnetic resonance (NMR), and in vitro/in vivo biological assays are discussed in detail. The review also highlights the importance of integrating multiple techniques to obtain reliable and reproducible data, which is essential for regulatory compliance and clinical translation of nanomedicines. Challenges and future perspectives in nanomedicine characterization are also addressed.
