They ingeniously combine the structural advantages of MOFs with the catalytic activity of ferrum, creating high-performance and tunable artificial enzyme mimics. Typically, ZIF-8 serves as the support or precursor, and ferrum species with enzyme-like activities are incorporated into its framework or pores via doping, loading, or in-situ synthesis strategies. The support\/matrix is ZIF-8, which is coordinated by zinc ions and 2-methylimidazole. It features a high specific surface area, regular pore structure, excellent chemical stability and biocompatibility. The active centers are mainly composed of ferrum, which predominantly exists in a mixed valence state of Fe³⁺\/Fe⁴⁺. This variable valence enables efficient catalysis of redox reactions, thereby mimicking the activity of natural enzymes. Technical Parameter Appearance Black powder Grain size 200-300 nm C content 80-85wt% (XPS) N content 3-5%wt% (XPS) O content 10-15wt% (XPS) Fe content 1-2wt% (XPS) Product Features 1)High catalytic activity: The Fe³⁺\/Fe²⁺ redox pair endows it with excellent multi enzyme mimicking activities. 2)Outstanding stability: The ZIF 8 framework provides physical protection and a confined space for the active sites, rendering this nanozyme more stable than free enzymes or bare ferium nanoparticles over a broad range of pH and temperature. 3)Tunable structure and activity: By altering synthetic conditions (e.g., dosage of ferrum source and reaction time), the size and morphology of ZIF 8, as well as the loading amount and valence state ratio of ferium, can be precisely regulated to tailor its catalytic performance. Application Fields 1)Tumor therapy: Leveraging the characteristics of the tumor microenvironment (e.g., high H₂O₂ concentration and acidic pH), peroxidase like (POD like) activity generates reactive oxygen species (ROS) to induce ferroptosis and apoptosis in tumor cells. 2)Antibacterial activity and wound healing: Reactive oxygen species are produced to disrupt bacterial structures for efficient bactericidal effects. Meanwhile, superoxide dismutase like (SOD like) and catalase like (CAT like) activities eliminate excess reactive oxygen species, alleviate inflammation, and facilitate tissue repair. 3) Biosensing: Benefiting from its outstanding peroxidase like and oxidase like activities, it catalyzes substrates to produce visible color changes, enabling highly sensitive and convenient detection. 4) Environmental remediation: Its peroxidase like activity mimics the Fenton reaction to activate H₂O₂ and degrade water borne organic pollutants such as dyes, phenols and antibiotics. The single atom sites deliver high catalytic efficiency without secondary iron sludge pollution.\u003c\/p\u003e","brand":"xfnano","offers":[{"title":"50mg D:200-300 nm 111203 \/ Store at room temperature in a dry, dark and sealed place \/ 180days","offer_id":57280577864058,"sku":"111203","price":156.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0907\/3606\/6938\/files\/1_27871cef-ce01-415a-9a0e-d29d5e516d17.png?v=1780024497","url":"https:\/\/chinanano.com\/products\/fe-single-atom-catalyst-zif-8-precursor","provider":"xfnano","version":"1.0","type":"link"}
