FIB design for nano-fluidic applications

In this paper we briefly review the techniques available to researchers in the nano-fluidic domain to fabricate nano-pores and nano-channels. In this context the focused ion beam (FIB) technique will be introduced as a useful and versatile tool for nano-fluidics. We illustrate it with two specific examples involving nano-pores as building blocks for nano-fluidics. Nano-pores, either biological, solid-state, or ultra thin pierced grapheme, are powerful tools which are central to many applications, from sensing of biological molecules to desalination and fabrication of ion selective membranes.
