An Investigation into the Intrinsic Peroxidase‐Like Activity of Fe‐MOFs and Fe‐MOFs/Polymer Composites

Abstract The quest for developing materials that provide a perfect trade‐off between factors such as enzyme‐like response, stability, and low cost has been long‐standing challenge in the field of biosensing. Metal‐organic frameworks (MOFs) their composites have emerged promising candidates biosensing applications due to exceptional properties tunable pore size, high specific surface area, exposed active sites. A comparative study intrinsic peroxidase‐like activity five different MOF materials: Fe‐BTC, NH 2 ‐MIL‐101(Fe), Fe‐BTC with polymers polydopamine (PDA), poly p‐phenylenediamine (PpPDA), poly(3,4‐ethylenedioxythiophene) is reported detection H O , an important biomarker biomedical diagnostics. response these toward via electrochemical colorimetric techniques mapped it found that, at neutral pH, Fe‐BTC/PEDOT composite exhibits highest sensitivity compared other this study. results indicate combination unique conducting polymer PEDOT, improves individual components. This work presents new opportunity easy‐to synthesize low‐cost MOFs/conducting provides significant insights achieve rational design desirable functional
