Expansion microscopy, or ExM, physically expands biological specimens upon embedding them in swellable polymeric hydrogels, allowing nanoscale imaging using conventional microscopes. This work presents a diamond lattice polymeric hydrogel synthesized via click chemistry, which achieves higher homogeneity than the ones currently in use, allowing a more accurate sample expansion.
