Multimodal X-ray imaging uncovers hierarchical mechanics in fibrous tissues

This study introduces TomoSAXS, a 3D small-angle X-ray scattering tomography technique that maps mechanics from fibril to fibre scale in intact tissues. The research focuses on intervertebral discs, revealing how molecular pre-strain in collagen fibrils contributes to the hierarchical load-bearing structure. These findings advance understanding of fibre mechanics in biological and engineered fibrous materials.
