Water pollution is a global concern for human and environmental health. As technology and industries have developed over the past decades, increasingly more complex and diverse pollutants are found even in treated waters. For better management of water resources, continuous and efficient monitoring is needed to detect the broad range of contaminants.

Biosensors have the potential to meet this challenge and to overcome the limitations of the conventional methods used for water analysis. They combine a biological recognition element to a transducer in a sensitive and robust device, capable of specific detection of molecules of interest. DNA-based sensing technologies meet this set of specifications and benefit from the progress made in nanoscience and nanotechnology. This mini-review proposes an overview of this upcoming new generation of DNA-based biosensors, focusing on promising innovations having for portable, stable, rapid and sensitive devices for water quality monitoring.

水污染是人类和环境健康的全球关注点。随着过去几十年技术和行业的发展，即使在经过处理的水中，也发现了越来越复杂和多样的污染物。为了更好地管理水资源，需要连续有效的监测以检测广泛的污染物。

生物传感器具有解决这一挑战并克服用于水分析的常规方法的局限性的潜力。他们将生物识别元件与灵敏且坚固的设备中的传感器结合在一起，能够特异性检测目标分子。基于DNA的传感技术符合这套规范，并受益于纳米科学和纳米技术的进步。这份小型综述对即将到来的新一代基于DNA的生物传感器进行了概述，重点介绍了用于便携式，稳定，快速和灵敏的水质监测设备的有希望的创新。
