Abstract
Methods and sensors for selective fluid sensing are provided. A sensor includes a resonant inductor-capacitor-resistor (LCR) circuit and a sensing material disposed over the LCR circuit. The sensing material includes a coordination compound of a ligand and a metal nanoparticle. The coordination compound has the formula: (X)-M, where X includes an alkylamine group having the formula (R—NH), an alkylphosphine having the formula (R—P), an alkylphosphine oxide having the formula (RP═O), an alkyldithiocarbamate having the formula (RNCS), an alkylxanthate having the formula (ROCS), or any combination thereof, R includes an alkyl group, n is 1, 2, or 3, and M includes the metal nanoparticle of gold, silver, platinum, palladium, alloys thereof, highly conductive metal nanoparticles, or any combination thereof. The sensing material is configured to allow selective detection of at least six different analyte fluids from an analyzed fluid mixture.
