Abstract
Dihydro-nicotinamide adenine dinucleotide (NADH) detection is crucial since it is a vital coenzyme in organism metabolism. Compared to the traditional method based on natural NADH oxidase (NOX), nanozymes with multienzyme-like activity can catalyze multistage reactions in a singular setup, simplifying detection processes and enhancing sensitivity. In this study, an innovative NADH detection method was developed using iron-doped carbon (Fe@C) nanozyme synthesized from metal-organic frameworks with in situ reduced Pt clusters. This nanozyme composite (Pt/Fe@C) demonstrated dual NOX and peroxidase-like characteristics, significantly enhancing the catalytic efficiency and enabling NADH conversion to NAD+ and H2O2 with subsequent detection. The collaborative research involving both experimental and theoretical simulations has uncovered the catalytic process and the cooperative effect of Fe and Pt atoms, leading to enhanced oxygen adsorption and activation, as well as a decrease in the energy barrier of the key step in the H2O2 decomposition process. These findings indicate that the catalytic performance of Pt/Fe@C in NOX-like and POD-like reactions can be significantly improved. The colorimetric sensor detects NADH with a limit of detection as low as 0.4 nM, signifying a breakthrough in enzyme-mimicking nanozyme technology for precise NADH measurement.
