Characterization of the dynamics of interfaces and of interface-dominated systems via spectroscopy and microscopy techniques

Complex interfaces, such as vesicles and biological membranes, and interface-dominated systems, such as foams and emulsions, are central to a vast range of naturally occurring and synthetic materials. In order to characterize their dynamics, it is necessary to cover a wide range of length and time scales. This can only be done by a combination of different techniques. We review here recent results and discuss new trends focusing on two class of techniques: correlation spectroscopies and microscopies, highlighting some examples of their combined use.
