Title: Miniature Chemical Sensor combining Molecular Recognition with Evanescent Wave Cavity Ring-Down Spectroscopy

Abstract

To address the chemical sensing needs of DOE, a new class of chemical sensors is being developed that enables qualitative and quantitative, remote, real-time, optical diagnostics of chemical species in hazardous gas, liquid, and semi-solid phases by employing evanescent wave cavity ring-down spectroscopy (EW-CRDS). The feasibility and sensitivity of EW-CRDS was demonstrated previously under Project No.60231. The objective of this project is to enhance the selectivity and range of application of EW-CRDS. Selectivity is achieved spectroscopically by using vibrational overtones in the near infrared and chemically by using modified surfaces to encourage selective adsorption of analyte while preventing non-selective adsorption. The range of application is expanded by extending EW-CRDS to liquids and by combining EW-CRDS with the unique optical properties of nanoparticles.
