Exhaled breath condensate based breath analyser – a disposable hydrogen peroxide sensor and smart analyser
Yu-Chih Chen, Danny O’Hare
Abstract
)sensor modified with a new composite consisting of Prussian Blue (PB), PEDOT:PSS, and crosslinker ethylene glycol (EG) and divinyl sulfone (DVS) combined with a thermoelectric EBC collection device. Theoretical modelling suggests that previously reported large variations between analyte concentrations arise from poor control of the condensation process. Experimental data confirm the model predictions and proof-of-principle human samples were analysed showing good agreement with fluorometric methods.
