Abstract
Rapid on-site measurements of arsenic (As) are essential for the timely remediation of As-contaminated groundwater for both municipal and emergency response applications. Current field tests suffer from either complicated end-user instructions or a lack of accuracy and specificity. The system presented here combines a whole-cell bacterial biosensor with an electrochemical measurement that provides enhanced accuracy and signal intensity compared to traditional bacterial-detection approaches. When integrated within a customized hardware system, this whole-cell sensor demonstrated excellent specificity and sensitivity. This fast, sensitive, and easy-to-use approach is a viable alternative for on-site arsenic testing.
