Hydrogen Peroxide Vapor Sensing with Organic Core/Sheath Nanowire Optical Waveguides

By decorating single crystal organic nanowires with H2O2‐reactive peroxalate ester, a core/sheath structure for the rapid and selective detection of H2O2 vapors is demonstrated via the optical waveguide of a single wire. Such a compact sensing configuration may act as the “nano‐alarm‐lamp” for the H...

Description
Summary:By decorating single crystal organic nanowires with H2O2‐reactive peroxalate ester, a core/sheath structure for the rapid and selective detection of H2O2 vapors is demonstrated via the optical waveguide of a single wire. Such a compact sensing configuration may act as the “nano‐alarm‐lamp” for the H2O2 vapors and be attractive for on‐chip optical detection in complex chemical or biological environments.
