X‐Ray Scattering Techniques Applied in the Development of Drug Delivery Systems

Abstract

The advances in nanotechnology have found application in different fields, such as food, agriculture, materials, chemistry, and medicine. However, one of the most important approaches is the development of nanocarriers and, in order to understand their structural organization, different physicochemical techniques have been used. In particular, small angle X-ray scattering (SAXS) and X-ray diffraction (XRD) have given important contribution to the study of organization phase of nanocarriers such as organic/inorganic nanoparticles, micelles, liposomes, cyclodextrins, polymers, and their interaction with drugs and other bioactive molecules. In this chapter, we will present theoretical aspects, experimental design, and the applications of both techniques for the development of delivery systems for bioactive molecules.
