Abstract: A living plant can function as self-powered auto-samplers and preconcentrators of an analyte within ambient groundwater, detectors of the analyte contained therein. For example, a pair of near infrared (IR) fluorescent sensors embedded within the mesophyll of the plant leaf can be used as detectors of the nitroaromatic molecules, with the first IR channel engineered through CoPhMoRe to recognize analyte via an IR fluorescent emission and the second IR channel including a functionalized nanostructure that acts as an invariant reference signal.
