Coupling High-Performance Thin-Layer Chromatography with Bacterial Genotoxicity Bioreporters

Environmental Science & Technology, 2019
We present an innovative technological platform for monitoring the direct genotoxicity of individual components in complex environmental samples, based on bioluminescent Escherichia coli genotoxicity bioreporters, sprayed onto the surface of a high-performance thin-layer chromatography (HPTLC) plate. These sensor strains harbor plasmid-borne fusions of
