Representative TEM images of nascent Mn oxide nanoparticles produced by Mnx. The reaction proceeded for 30 min at a substrate to enzyme molar ratio of 5000:1. a Agglomerated forms of nanoparticles (crystallites). Individual crystallites are ~1.1–4.2 nm in length, with an average diameter of 2.3 ± 0.7 nm. b Atomic resolution TEM revealed three distinct forms of nanocrystalline material: amorphous clusters consisting of individual Mn atoms (arrows), individual nanocrystals (dashed circle), and agglomerations of crystallites forming lath-like crystals (dashed rectangle—notice the MnOx atomic rows). Scale bars are 2 nm
