Neutrons for the study of dynamics in soft matter systems

Neutron scattering is a valuable tool not only in studying the structure but also the dynamics of nanoscale soft matter systems. By combining different neutron scattering methods, it is possible to observe energy changes from millielectronvolt to nanoelectronvolt. A unique advantage of neutron scattering is the possibility to highlight different parts of a system simply by changing its isotopic composition, allowing to study specific parts of complex systems. This review tries to give an overview of the possibilities of neutron scattering methods together with some recent examples, mostly from neutron spin-echo spectroscopy, which is the method allowing to measure the smallest changes in energy.
