Creative Enzymes provides services to customers worldwide in the field of the construction of cerium-based nanozymes. Our platform is equipped with cutting-edge facilities and professional experts to support nanozyme research. Here, we provide various services according to customers' requirements.
| Nanozymes Features | Mimical Enzyme Activity | |
|---|---|---|
| Cerium Oxide (CeO2) Nanozymes | An ideal material for nanozyme because it not only has excellent biocompatibility; but also has ample oxygen vacancies that can realize the valence conversion between Ce3+ and Ce4+. | Catalase-like and superoxide dismutase |
| CeVO4 Nanozymes | The enzyme activity of the CeVO4 nanozymes depends on the relative ratio of surface Ce3+ / Ce4+ ions, the presence of V5+ and the surface-Cyt c interactions. | Cytochrome c oxidase (CcO) and superoxide dismutase |
| Pt / CeO2 Nanozymes | The property of strong stabilization is related to the stability of Pt2+ ions within square-planar [PtO4] moieties on the surface of nanostructured CeO2. | Catalase-like and superoxide dismutase |
| MOF / Ce Nanozymes | MOF / Ce nanozymes are of special interest due to the combination of microporosity, the Ce(III) / (IV) redox properties and the presence of low-energy 4f orbitals. | Heterogeneous catalysis and heterogeneous photocatalysis |

We provide CeVO4 nanozymes using synthetic methods such as solvothermal, sonochemical, hydrothermal and other methods. It can form different structures, for example cube-like, tiny flake-like and so on.
The most common strategies for the synthesis of MOF / Ce nanozymes are based on the use of water and / or DMF in solvothermal reactions and employing Ce(NO3)3 · 6H2O or CeCl3 as the metal source.
After the construction of cerium-based nanozymes, we also provide determination of peroxidase activity, catalase activity, superoxide dismutase activity and others, measure of catalytic kinetics data as well as stability tests. Our one-step service will help our clients make progress in research.
Creative Enzymes provides cost-effect, high quality and hassle-free services to our clients worldwide. We provide our clients with direct access to our experts as well as prompt respond to their inquiries. If you are interested in our services, please feel free to contact us or make online inquiry.
