Field-Assisted Sensitivity Amplification in a Noble Metal Nanoparticle Decorated WO3/GO Hybrid FET-Based Multisensory Array for Selective Detection of Breath Acetone

Abstract

The current work shows noble metal (Au, Pd and Pt) nanoparticles, WO3 and graphene oxide based ternary hybrid field effect transistor structured sensor array for the selective detection of breath acetone. Accurate acetone selectivity was achieved by using phase space entire based feature extraction techniques. Field-assisted sensitivity amplification was responsible for the detection of ppb to lower ppm level detection of acetone.
