Nanozymatic platform for dual colorimetric and fluorimetric sensing of H₂O₂ and glucose using Ni-CoWO₄ nanoparticles (opens in new tab)

Hydrogen peroxide (H₂O₂) plays a crucial role in both biological and industrial systems. Excessive H₂O₂ can lead to oxidative stress, cellular damage, and process-related issues in manufacturing. For this reason, fast and sensitive detection methods are needed. In this study, Ni-CoWO₄ nanoparticles, belonging to the bimetallic nanozymes family, were used as catalysts to promote the oxidation of ortho-phenylenediamine (OPD) by H₂O₂. Polyoxometalates are renowned for their structural diversity,...
