A novel fabrication of water-dispersible polyaniline-poly(4-styrenesulfonate) (PANI–PSS) nanoparticles with an average diameter ca. 30 nm is presented. PANI–PSS can be easily processed and thus used in inkjet-printed chemical sensors (an image shown the figure). These shows unprecedented sensitivity rapid response time compared to conventional PANI-based sensors.
