Sensitive on-chip methane detection with a cryptophane-A cladded Mach-Zehnder interferometer.
We report a methane sensor based on an integrated Mach-Zehnder interferometer, which is cladded by a styrene-acrylonitrile film incorporating cryptophane-A. Cryptophane-A is a supramolecular compoundExpand
