Abstract
The rapid and simple detection methods of hydrogen peroxide (H2 O2 ) residues is highly required for food safety. Herein, an electrochemical H2 O2 sensor is developed with cerium oxide nanocubes as highly active non-enzymatic catalyst. Combined with carbon black to improve conductivity, the disposable sensor can determine H2 O2 in the range from 100 to 100 μM with a limit of detection (LOD) of 100 nM. This sensor also shows good selectivity and reproducibility, which is enabled to detect H2 O2 in real food samples without any pretreatment in 100 s, providing a new solution for the direct quantitative measurement of H2 O2 residues for food safety. © 2024 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.
基于纳米氧化铈的非酶电化学传感器用于快速检测食品样品中的过氧化氢残留量†.
食品安全对过氧化氢（H2O2）残留的快速、简单检测方法有很高的要求。本文以纳米氧化铈为高活性非酶催化剂，开发了一种电化学 H2O2 传感器。这种一次性传感器与提高导电性的碳黑相结合，可测定 100 至 100 μM 范围内的 H2O2，检测限 (LOD) 为 100 nM。该传感器还具有良好的选择性和再现性，无需任何预处理，100 秒内就能检测真实食品样品中的 H2O2，为直接定量检测 H2O2 残留提供了新的解决方案，从而保障食品安全。© 2024 日本电气工程师学会和 Wiley Periodicals LLC。
