| titleOfInvention | Equilibrium Plasmonic Analyte Sensing Apparatus and Methods |
| abstract | Apparatus and methods are provided for quantitative detection of mercury vapor in gas samples using a film of nanoparticles. The localized surface plasmon resonance (LSPR) of an amalgam nanoparticle is sensitive to adsorbed mercury mass. The equilibrium mass of mercury on a gold nanoparticle is a function of the surrounding vapor concentration and the temperature of the gold. A device that introduces a temperature-controlled gold nanoparticle film to a controlled flow of sample gas responds predictably to a given mercury vapor concentration when optically probed in situ. Controlling the temperature of the film allows for control of adsorption and desorption rates. Equilibrium plasmonic mercury detection, described herein, removes the cycling necessary for many gold-based mercury analyses. Methods are given for the operation and analysis of the temperature-stabilized gold nanoparticle mercury sensor. The disclosed mercury-detection apparatus and methods find use in a variety of applications, including, for example, mercury detecting applications. |
