A Suspended Au Nanowire Bridge with Functionalized Self-Assembled Monolayers (SAMs)

In this paper, a very simple top-down nanofabrication method, which is compatible with standard silicon (Si) fabrication processes, is proposed to fabricate a new suspended gold (Au) nanowire bridge. The electrical characteristics of the nanowire bridges with different design parameters are measured. The realized nanowire bridge has shown a high potential for biomolecular detection by mechanical, electrical or optical sensing mechanism through the formation of functionalized self-assembled monolayers (SAMs) on the bridge structure.
