Gallic acid nanoflower immobilized membrane with peroxidase-like activity for m-cresol detection.

ABSTRACT: We report fabrication of new generation nanoflowers (NFs) using gallic acid (GA) and copper (II) ions (Cu²⁺) acted as an organic and inorganic component, respectively with effective peroxidase mimic activities in solution and on filter membrane. Unlike the typical protein NFs synthesis mechanism, gallic acid NFs (GA-NFs) was formed via coordination reaction between carboxyl groups of GA and Cu²⁺. The different morphologies of the GA-NFs were acquired based upon whether the carboxyl groups in gallic acid are active or not. The peroxidase mimic activity of the GA-NFs relied on the Fenton reaction in the presence of hydrogen peroxide (H₂O₂) was tested towards m-cresol as a function of concentration of the GA-NFs, m-cresol, H₂O₂
