Copper Ion Genetic Biosensor: A Synthetic Biology Approach for Environmental Heavy Metal Detection

2025-07-25

Abstract excerpt

<title>Abstract</title> <p>Excess environmental copper from industrial and agricultural sources poses significant risks to ecosystems and human health. We engineered a whole-cell <italic>Escherichia coli</italic> biosensor to rapidly detect bioavailable Cu(II) ions using a copper-inducible genetic circuit. The system couples the <italic>E. coli</italic> copA promoter – a copper- responsive regulatory element – to...
