Multienzyme Mimicking Cascade Mn3O4 Catalyst to Augment Reactive Oxygen Species Elimination and Colorimetric Detection: A Study of Phase Variation upon Calcination Temperature

“…So, several strategies have already been developed to increase the efficiency of nanozyme activity, but to date, the effect of the calcination temperature on the nanozyme activity has not been explored. Direct calcination to the metal oxide creates oxygen vacancies and tunes rearrangement of the electronic configuration; therefore, an oxygen-vacancy-mediated mixed-valence oxide was directly obtained by calcination of the metal oxide. − Moreover, for particular Mn 3 O 4 NPs, the new phase appeared after calcination to 550 °C, and many studies have suggested that Mn 3 O 4 NPs transformed to Mn 5 O 8 after calcination to 550 °C.…”

Enzyme Mimetic Activity of Intercalated Pd–H Nanosheets for Bioanalysis

“…Macromolecular biocatalysts, named enzymes found in living organisms and mainly composed of proteins, are responsible for regulating the possible chemical reactions in living organisms . Owing to their high substrate specificity and catalytic activity, natural enzymes have been extensively used in biological fields, industry, medicines, etc. − However, their low stability, high cost, and complex production process increase the demand for artificial enzymes, which are proven to be promising candidates in the fields of nanotechnology, , biotechnology, , and nanomaterials science. , Enzyme-like activities of nanozymes, such as oxidase-like, − peroxidase-like, − and catalase-like, , have been explored through various studies. Furthermore, nanozymes have been explored for the antibacterial activity at physiological pH in the presence of adenosine triphosphate (ATP) .…”
