Title: Development of a luminescence based N-nitrosamines sensor and a methane preconcentrator

Abstract: The development of miniaturised, affordable sensors as an alternative to specialised analytical laboratories allows for their widespread deployment in areas of concern, facilitating citizen science and has the potential to give a higher spatiotemporal resolution. Our lab has previously developed different optical and chemiresistive sensors targeting a wide variety of analytes, but there still exist challenges to overcome, such as reduced performance at high humidity levels. My work in the group has been to develop new sensing platforms for some of these environmentally relevant analytes, such as N-nitrosoamines and methane. I will initially present on the synthesis and sensing performance of a group of binuclear copper (I) complexes for the luminescent detection of N-nitrosamines. Afterwards, my presentation will shift towards the development of a potential methane preconcentrator based on a porous hydrocarbon polymer. The hydrophobicity of this material may be beneficial in reducing undesired humidity effects.
