Neutron scattering has been used more and more widely, as neutron sources and scattering techniques have been developed. For the basic properties of the neutron the usefulness of neutrons scattering is better than other scattering techniques (X-Ray scattering, Raman scattering etc.) at a lot of areas especially in biopolymer studies. Because firstly, H has a very big neutron scattering cross-section as neutron scattering can tell us the site of H and H-bond distinctly and it is very important in the researches of the biopolymer structures. Secondly, neutron can distribute H and D for they have different neutron scattering cross-sections, so we can use isotopic substitution at studies, it is very useful for the researches of compound biopolymers and a lot of biopolymers are compounds. At the same time biopolymers' dynamic behaviors can be obtained by neutron scattering too. In this paper the applications of neutron scattering in biopolymers including structure and dynamics of biomacromolecules are reviewed.
