Abstract
The biochemical oxygen demand (BOD) is critical for assessing water quality, linking the quantity of biodegradable organic carbon with pollution levels. Electrochemical biosensors have shown great improvements over traditional BOD measurement methods by offering the advantages of simplicity, rapid response, high sensitivity, and real-time monitoring. In this review, we discuss different types of BOD electrochemical biosensors, including oxygen electrode-, microbial fuel cell (MFC)-, and microbial electrolysis cell (MEC)-type sensors, focusing on recent advances in microbial community composition, electrode materials, and optimization approaches. Moreover, current challenges in developing effective electrochemical biosensors for BOD detection are presented to meet diverse sample needs.
生化需氧量(BOD)是评估水质的关键,它将可生物降解有机碳的数量与污染程度联系在一起。与传统的 BOD 测量方法相比,电化学生物传感器具有操作简单、反应迅速、灵敏度高和可实时监测等优点,因而有了很大的改进。在这篇综述中,我们讨论了不同类型的 BOD 电化学生物传感器,包括氧电极、微生物燃料电池 (MFC) 和微生物电解池 (MEC) 型传感器,重点介绍了微生物群落组成、电极材料和优化方法方面的最新进展。此外,还介绍了目前在开发用于 BOD 检测的有效电化学生物传感器以满足不同样品需求方面所面临的挑战。
期刊介绍:
Sensing and Bio-Sensing Research is an open access journal dedicated to the research, design, development, and application of bio-sensing and sensing technologies. The editors will accept research papers, reviews, field trials, and validation studies that are of significant relevance. These submissions should describe new concepts, enhance understanding of the field, or offer insights into the practical application, manufacturing, and commercialization of bio-sensing and sensing technologies.
The journal covers a wide range of topics, including sensing principles and mechanisms, new materials development for transducers and recognition components, fabrication technology, and various types of sensors such as optical, electrochemical, mass-sensitive, gas, biosensors, and more. It also includes environmental, process control, and biomedical applications, signal processing, chemometrics, optoelectronic, mechanical, thermal, and magnetic sensors, as well as interface electronics. Additionally, it covers sensor systems and applications, µTAS (Micro Total Analysis Systems), development of solid-state devices for transducing physical signals, and analytical devices incorporating biological materials.
