Enhancing Oxidase‐Catalyzed Biosensing via Hydrophobic ZIF‐7 Nanomaterials: A Micro‐Triphase Interface Approach
The study introduces ZIF-7 nanoparticles as hydrophobic oxygen reservoirs in a solid–liquid–air triphase enzyme electrode, boosting oxidase‑catalyzed biosensing. By releasing pre‑stored O₂, the system raises Vmax 21‑fold and widens the glucose linear range from 2 mM to 20 mM, a ten‑fold improvement over conventional diphase designs. The approach is generalizable to other biomolecule detections and offers a practical solution to oxygen limitation in electrochemical sensors.
