Nanozymes that display multiple activities have received increasing attention because they can be applied more widely than single-active nanozymes. In this paper, we demonstrated that the as-prepared V6O13 nanotextiles (NTs) with interlaced network structure possess triple-enzyme mimetic activity for the first time. The intrinsic oxidase-like, peroxidase-like, and catalase-like catalytic behavior of V6O13 NTs was investigated. Michaelis–Menten kinetics and high affinity for TMB and H2O2 was observed, indicating that V6O13 NTs can be used as enzyme mimics. These multiactivity V6O13 NTs were robust, inexpensive, and easily prepared. Based on the oxidase-like and peroxidase-like activity, a colorimetric biosensor for the glutathione (GSH) detection and a fluorescent system for the detection of H2O2 and glucose were established. The detection of GSH and glucose in health supplements and human serum samples was successfully applied through the proposed method.

V 6 O 13纳米纺织物的内在三酶模拟活性：机理研究以及比色和荧光检测
表现出多种活性的纳米酶受到越来越多的关注，因为它们可以比单活性纳米酶得到更广泛的应用。在本文中，我们证明了所制备的具有交错网络结构的V 6 O 13纳米织物（NTs）首次具有三酶模拟活性。研究了V 6 O 13 NTs的固有氧化酶样，过氧化物酶样和过氧化氢酶样的催化行为。观察到Michaelis-Menten动力学和对TMB和H 2 O 2的高亲和力，表明V 6 O 13 NTs可以用作酶模拟物。这些多功能V 6 O 13NT坚固，便宜且易于制备。基于氧化酶样和过氧化物酶样活性，建立了用于谷胱甘肽（GSH）检测的比色生物传感器和用于检测H 2 O 2和葡萄糖的荧光系统。通过该方法成功地检测了健康补品和人血清中的谷胱甘肽和葡萄糖。
