A wide variety of neutron scattering techniques can be applied to obtain information on the structure and dynamics of biological systems on multiple scales. Recent progress is summarized, as are hoped-for future developments in the context of the advent of next-generation neutron sources on various continents.

Rules for the experimental design of scattering contrast in reflectometry experiments of biological surface architectures are derived using an information theoretical framework.

A framework for the optimization of neutron reflectometry experiments based on Bayesian statistics and information theory is presented.
