173MoO3 NPsAcid phosphatase (ACP) catalyzes the hydrolysis of the ascorbic acid 2-phosphate (AAP) substrate to produce ascorbic acid (AA). AAwas found to fade the coloration process of the MoO3 NP-mediated ABTS oxidation. By combining the oxidase-mimicking property of the MoO3 NPs and the ACP-catalyzed hydrolysis ofAAP, a novel and simple colorimetric method for detecting ACP was establishedAcid phosphatase (ACP)Color0.09-7.3U/L0.011U/L92-107.6%
