An intriguing system featuring a wide band gap silica nanowire (SiO x NW) that absorbs visible light (532 nm) via the surface plasmons (SPs) of embedded gold nanoparticles (Au NPs) is reported for sensing applications. We report SP resonance-enhanced molecular oxygen sensing by single Au-NPs@SiO x N...
