Abstract

We report on a highly sensitive plasmon-based nanosensor. This hybrid sensor is composed of a glass tip with a set of gold nanoparticles grafted at its apex. It allows to optimize the excitation and detection of the localized surface plasmon resonance of metal nanoparticles and thus to increase dramatically the sensitivity. First results show the possibility to detect a concentration as low as 10^-10 M on a single gold dimer. Furthermore, promising SERS measurements are reported.
