The detection of ultralow concentrations of molecules using nanoscale optical sensors is hindered by the difficulty in bringing the two into contact, where diffusion acts on impractical timescales. Fortunately, introducing plasmonic structures to super-hydrophobic surfaces may offer a way around this problem.
