Abstract

A core/sheath structure is fabricated by decorating single-crystal organic nanowires with H2O2-reactive peroxalate ester, as reported by J. Yao, Y. S. Zhao, and co-workers on page OP194. The shell of the nanocable is highly sensitive and selective to the H2O2 molecules, demonstrated by the generation of chemiluminescence on exposure to H2O2 vapors. The cable-like optical waveguide sensing platform can rapidly and selectively monitor H2O2 vapors through the amplified optical variation across the wire waveguiding, showing that a single nanocable is very promising for developing optical probes to detect individual responses on-chip.
