A solution as well as solid state based sensor has been developed for selective detection of picric acid (PA) in water. Oligo (p-phenylenevinylene) (OPV) incorporated polystyrene nanobeads (PS-OPV-NH₂) having an average size of 180 nm have been synthesized through miniemulsion polymerization. Amine (–NH₂) functionalization was performed on the nanobead surface to enhance the efficiency of the sensor among a library of other nitro-organics and library of cations and anions.
