A novel approach is explored to result in anion selective nanostructural optodes, that do not require the presence of selective ionophore. The sensing principle proposed is based on interactions of polarity sensitive dye with anions, leading to change of the chromophore group environment, resulting in increase of emission for increase of analyte concentration. To induce interactions of the analyte with the dye precise matching of properties of analyte and receptor is required.

A challenge in turn-on mode operating optodes application is elimination of pH sensitivity. The polyoctylthiophene based optodes response mechanism is not involving hydrogen ions exchange, thus paves the way for optodes applicable for sensing in wide pH range. We report on nanoptodes that can be used both in alkaline and in acidic pH range inaccessible for classical systems using pH sensitive dyes as transducers.
