Approaches used to design toxicity sensors and arrays. (a) Polyion-DNA-enzyme film formation by the layer-by-layer method. (b) Example of a pathway of molecular bioactivation leading to a toxic metabolite that reacts with DNA. Abbreviations: CE-LIF, capillary electrophoresis–laser-induced fluorescence; cyt, cytochrome; ECL, electrochemiluminescence; LC-MS, liquid chromatography–mass spectrometry.
