The electrical impedance change and response time of chemiresistor sensors based on gold nanoparticles capped with 1-hexanethiolate ligands were investigated for several organic analytes dissolved in aqueous solution. Analytes that partitioned strongly into the nanoparticle film resulted in greater impedance changes and longer response times than analytes which had a smaller partition coefficient.
