Our manuscript describing array sensing methods for the detection of azo dyes, common pollutants in industrial wastewaters, was accepted for publication in ACS Sensors. The work was conducted by Michael Ihde in our group, in collaboration with Josh Tropp in the Azoulay research group from the School of Polymer Science and Engineering at the University of Southern Mississippi. The method relies on purpose-built emissive fluorene conjugated co-polymers. These materials were decorated with pendant arms that changed the position and intensity of the polymers' absorption bands, producing a family of highly fluorogenic materials whose fluorescence modulation by non-specific interactions with dye analytes through the inner-filter effect (IFE) led to the successful discrimination of 12 chemically similar azo dyes in water.
