Abstract
The neutron and X-ray scattering techniques of small-angle scattering and reflectivity are important tools for the characterisation of the key properties of surfactants, their adsorption at interfaces, and their self-assembly in solution. The increasing trend towards biosustainable and biocompatible surfactant-based formulations highlights the increasing importance of understanding the properties of biosurfactants. This review focuses on some relatively recent contributions of the use of primarily neutron scattering techniques to the understanding of surface adsorption and self-assembly of some specific microbial derived biosurfactants, rhamnolipids and sophorolipids. The review also focuses on the behaviour of their mixtures with other surfactants and shows how a detailed thermodynamical analysis is possible from the scattering data.
期刊介绍：
Current Opinion in Colloid and Interface Science (COCIS) is an international journal that focuses on the molecular and nanoscopic aspects of colloidal systems and interfaces in various scientific and technological fields. These include materials science, biologically-relevant systems, energy and environmental technologies, and industrial applications.
Unlike primary journals, COCIS primarily serves as a guide for researchers, helping them navigate through the vast landscape of recently published literature. It critically analyzes the state of the art, identifies bottlenecks and unsolved issues, and proposes future developments.
Moreover, COCIS emphasizes certain areas and papers that are considered particularly interesting and significant by the Editors and Section Editors. Its goal is to provide valuable insights and updates to the research community in these specialized areas.
