X-ray imaging at under 40 nm resolution without destroying the tissue: a demonstration by Wanner, Díaz, Schaefer and Bosch.
Based on radiation-had epoxy resin borrowed from the aerospace and nuclear industries.
"Tissue samples were resistant to radiation doses exceeding 1.15 × 1010 Gy, and sub-40 nm isotropic resolution allowed identifying axon bundles, dendrites and synapses in mouse brain tissue without physical sectioning."
"Nondestructive X-ray tomography of brain tissue ultrastructure", Bosch et al. 2025
