A sensor fabricated from the inkjet-printed deposition of polyaniline nanoparticles onto a screen-printed silver interdigitated electrode was developed for the detection of ammonia in simulated human breath samples. Impedance analysis showed that exp... Read More about Direct measurement of ammonia in simulated human breath using an inkjet-printed polyaniline nanoparticle sensor.

Taking a breath for better health (2013)
Journal Article
Killard, A. (2013). Taking a breath for better health

What does your breath say about you? It might tell the world (or at least anyone at close quarters) that you didn’t brush your teeth this morning, or that you ate garlic last night. But there might also be other, subtle and important clues in there a... Read More about Taking a breath for better health.
