Forbes: The National Science Foundation is backing a pilot study by Northwestern University to develop and distribute water quality testing kits to Chicago-area residents. Other big cities could be next.
The foundation awarded a $3 million grant to the university. Later this year, 350 households will receive handheld, easy-to-use test kits to assess their home water quality. The tests will be available first for lead, and later for copper and PFAS.

Cell-free biosensors are powerful platforms for monitoring human and environmental health. Here, we expand their capabilities by interfacing them with toehold-mediated strand displacement circuits, a dynamic DNA nanotechnology that enables molecular computation through programmable interactions between nucleic acid strands. We develop design rules for interfacing a small molecule sensing platform called ROSALIND with toehold-mediated strand displacement to construct hybrid RNA–DNA circuits that allow fine-tuning of reaction kinetics.

Lack of access to safe drinking water is a global problem, and methods to reliably and easily detect contaminants could be transformative. We report the development of a cell-free in vitro transcription system that uses RNA Output Sensors Activated by Ligand Induction (ROSALIND) to detect contaminants in water. A combination of highly processive RNA polymerases, allosteric protein transcription factors and synthetic DNA transcription templates regulates the synthesis of a fluorescence-activating RNA aptamer.

Tracking progress towards Target 6.1 of the United Nations Sustainable Development Goals, “achieving universal and equitable access to safe and affordable drinking water for all”, necessitates the development of simple, inexpensive tools to monitor water quality.
