In Japan, discharge of organic effluents—biodegradable waste materials from plants and animals—into freshwater bodies is a significant environmental concern, affecting the health and sustainability of these aquatic ecosystems. However, the methods currently available for inspecting water quality are complex and costly.
In this regard, researchers from Ritsumeikan University, Japan, have recently developed a self-powered, inexpensive, and floating biosensor for monitoring water quality at the input of freshwater lakes and rivers. This paper was made available online on September 9, 2023, and was published in Volume 200 of the Biochemical Engineering Journal on November 1, 2023.
