P1.7.14 Au nanoelectrodes below nanostructured SnO2 films for acetone detection during breath analysis

M. Righettoni, A. Tricoliand & S. E. Pratsinis
New medical diagnostic methods such as non-invasive breath analysis bear the potential of drastically reducing medical costs as a greater amount of automatization is possible. Here, an asymmetric electrode assembly is described that increases the SnO2sensitivity and selectivity to acetone, a tracer for diabetes type-1, and reduces the resistance of the nanostructured SnO2layer. Gold nanoparticles serving as nanoelectrodes are stochastically deposited by flame spray pyrolysis (FSP) below a functional film decreasing the effective length of...
