The applicability of time-of-flight spin-echo small-angle neutron scattering to the study of the inner fractal structure of the nuclei of biological cells is demonstrated. The method is used to show the logarithmic fractal structure of the large-scale organization of chromatin in rat lymphocyte nuclei.

The use of the BILMIX program to model small-angle X-ray scattering data of model membranes and deliver a description of the lipid bilayer electron density and vesicle size distribution is presented.
