Zinc oxide nanoparticles induce transient morphological transformation in Escherichia coli from the native ∼ 2–4 μm rods to 20–40 μm filamentous cells as reported by Rose Amal and co‐workers. The filamentation is induced only in response to the solid ZnO residues, while non‐observable in the presence of the leached zincpeptide complexes. Free zinc ions induce severe cell rupturing.
