Programmable Bacterial Sensors Detect Target Contaminants in Real Time

Posted by in category: electronics

Programmable bacteria attached to electrodes that deliver a electrical signal when the bacteria detect a target contaminant, enables real-time sensing, reports a study from Rice University. The engineered E.coli and electrodes are encapsulated in an agarose capsule to prevent the bacteria from falling off the electrodes. Prototypes developed by the team can detect contaminants in water such as thiosulfate and an endocrine disruptor in under five minutes.
