Cindy Gunawan, Wey Yang Teoh, Ricardo, Christopher P. Marquis and Rose Amal Nanoparticles: Zinc Oxide Nanoparticles Induce Cell Filamentation in Escherichia coli (Part. Part. Syst. Charact. 4/2013) Particle & Particle Systems Characterization 30
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.
