Miniature Chemical Sensor Combining Molecular Recognition with Evanescent Wave Cavity Ring-Down Spectroscopy
To address DOE's chemical sensing needs, a new class of chemical sensors is being developed to enable 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 (EWCRDS). The sensitivity of EW-CRDS was demonstrated previously under Project No.60231. The objective of this project is to achieve highly selective chemical detection in a complex matrix of interferants by combining EW-CRDS with molecular recognition (MR) chemistry and by exploiting the polarization dependence of EW-CRDS to enhance optical selectivity.
