     in recent years, much research has focused on the development of low-cost, printed electrochemical sensor platforms for environmental monitoring and clinical diagnostics. much effort in this area has been based on utilising the redox properties of conducting polymers, particularly polyaniline (pani). in tackling the inherent lack of processability exhibited by these materials, several groups have examined various mass-amenable fabrication approaches to obtain suitable thin films of pani for sensing applications. specifically, the approaches investigated over the years include the in situ chemical synthesis of pani, the use of sulphonated derivatives of pani and the synthesis of aqueousbased nano-dispersions of pani. nano-dispersions have shown a great deal of promise for sensing applications, given that they are inkjet-printable, facilitating the patterning of conducting polymer directly to the substrate. we have shown that inkjet-printed films of pani can be finely controlled in terms of their two-dimensional pattern, thickness, and conductivity, highlighting the level of precision achievable by inkjet printing. utilising these nanomaterials as inkjet-printable inks opens novel, facile, and economical possibilities for conducting polymer-printed electronic applications in areas of sensing, but also many other application areas such as energy storage, displays, organic light-emitting diodes. given that inkjet-printing is a scalable manufacturing technique, it renders possible the large-scale production of devices such as sensors for a range of applications. several successes have emerged from our work and from the work of others in the area of applying pani in low-cost sensor applications, which is the focus of this review.
