Abstract:

In this work, novel Cu2V4O11 nanorods (CVNRs) were meticulously synthesized employing an exquisite one-pot hydrothermal technique, thereby endowed with an inherent peroxidase-like prowess capable of catalyzing the oxidation of 3,3 ',5,5 '-tetramethylbenzidine (TMB) to produce a blue color reaction in the presence of H2O2. Kinetic examinations revealed that CVNRs exhibited a 3.36-fold increased affinity for TMB in comparison to the natural enzyme horseradish peroxidase, and the catalytic response derived from CVNRs adhered to a ping-pong mechanism. Free radical trapping experiments corroborated the pivotal role of center dot O2- radicals in establishing the dominant oxidant for TMB oxidation. Hence, a sensitive visual assessment platform, grounded in CVNRs, was engineered for the detection of H2O2 and glucose. The limit of detection for H2O2 and glucose were 0.054 mu M and 2.24 mu M, respectively, and the detection ranges were 1-50 mu M and 10-75 mu M, respectively. Most notably, the visual platform harbored exceptional stability, selectivity, and anti-interference capabilities. This research not only bestows upon CVNRs an extraordinary capability to discern H2O2 and glucose within practical samples, but also expands the realm of application for CVNRs in the domains of environmental preservation, forensic science and biomedical diagnosis.
