环境污染监测需要快速、可靠、经济高效且小型的设备。这种需求解释了污染物检测生物传感设备的最新发展趋势。本综述旨在总结使用生物传感器检测环境污染物的最新趋势。讨论了酶、全细胞、抗体、适体和基于 DNA 的生物传感器和仿生传感器。我们总结了它们在检测各种污染物方面的适用性,并提到了它们的建设性特点。生物传感器设计中使用了多种检测原理:电流测定法、电导测定法、发光法等。它们在速度、灵敏度、盈利能力和设计方面有所不同。每一种都具有特定的选择性和检测限,具体取决于敏感元件。模拟生物传感器由于其与传统生物传感器相比的优势,逐渐受到研究人员和用户的关注。需要进一步的研究来开发强大的生物传感装置,这些装置可以成功地用于检测复杂基质中的污染物,而无需事先制备样品。
The monitoring of environmental pollution requires fast, reliable, cost-effective and small devices. This need explains the recent trends in the development of biosensing devices for pollutant detection. The present review aims to summarize the newest trends regarding the use of biosensors to detect environmental contaminants. Enzyme, whole cell, antibody, aptamer, and DNA-based biosensors and biomimetic sensors are discussed. We summarize their applicability to the detection of various pollutants and mention their constructive characteristics. Several detection principles are used in biosensor design: amperometry, conductometry, luminescence, etc. They differ in terms of rapidity, sensitivity, profitability, and design. Each one is characterized by specific selectivity and detection limits depending on the sensitive element. Mimetic biosensors are slowly gaining attention from researchers and users due to their advantages compared with classical ones. Further studies are necessary for the development of robust biosensing devices that can successfully be used for the detection of pollutants from complex matrices without prior sample preparation.
