5082 173 MoO3 NPs Acid 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 established Acid phosphatase (ACP) Color 0.09-7.3 U/L 0.011 U/L 92-107.6%
