Advanced Materials, Volume 35, Issue 42, October 19, 2023., 2023 Within live cells, DTTO molecules form amorphous spherical clusters which subsequently accumulate, coalesce, and lead to the formation of fibrous crystals interconnecting different cells. Remarkably, cells produce a distinctive crystalline form, that is, a bio‐polymorph, which cannot be replicated outside cells.
