Nanocomposite of MgFe₂O₄ and Mn₃O₄ as Polyphenol Oxidase Mimic for Sensing of Polyphenols.

ABSTRACT: Polyphenol oxidase (PPO) mimics have advantage of detection and remediation of polyphenols. This work demonstrates rapid and sensitive colorimetric detection of phenolic compounds using nanocomposite of magnesium ferrite (MgFe₂O₄) and manganese oxide (Mn₃O₄) nanoparticles as PPO mimic. The catalytic properties of MgFe₂O₄ and Mn₃O₄ displayed synergistic effect in the nanocomposite. The synthesized nanocomposite and nanoparticles were fully characterized using various analytical techniques. The ratio of MgFe₂O₄ and Mn₃O₄ in the nanocomposite was optimized. Catechol and resorcinol were taken as model polyphenols. The best PPO-activity was shown by MgFe₂
