Zif-coupled Microresonator for Highly Sensitive and Selective Gas Detection
نویسندگان
چکیده
We introduce for the first time a zeolitic imidazolate framework (ZIF)-coupled resonant gas sensor whose sensitivity shows an improvement up to 78 times over silicon resonant sensors with identical dimensions while additionally utilizing the inherently selective adsorption properties of ZIFs. In order to achieve high sensitivities, a resonator needs to have a high surface-to-volume ratio. In this study, we demonstrate a microresonator coupled with ZIF crystals, which provide a level of surface area that was previously unachievable, as well as the potential for inherent selectivity.
