Repurposing the Sb(III)-specific efflux and sequestration system (ant operon) to mitigate antimonite cross-talk in ArsR-based bacterial arsenite sensors

ArsR-based whole-cell biosensors offer sensitive colorimetric detection of arsenite [As(III)], yet their broad reactivity toward Group 15 metalloids—especially antimonite [Sb(III)]—limits field specificity. Th…
