title: A single-nanoparticle NO2 gas sensor constructed using active molecular plasmonics.
abstract: A single-nanoparticle plasmonic sensor for the sensitive detection of gas molecules (NO2) has been constructed. Taking advantage of active molecular plasmonics, the analyte selectively triggers a measurable spectral shift of ferrocene-modified single gold nanorods.
