Terahertz electrical and optical characteristics of double-walled carbon nanotubes and their comparison with single-walled carbon nanotubes

In Research Profile: Reliable dispensing of attoliter volumes of fluid, Stephen Jacobson has been hashing out some of the basic infrastructure of this nanorealm. An initial step “is to see how well things from the microfluidic regime scale to the nanofluidic regime,” Jacobson says. “What can you transfer from microfluidics to nanofluidics, and does it work?”

Microfabricated Fabry–Pérot interferometer with nanochannels

As nanochannels become thinner than ~20
nm, optical microscopy can’t distinguish
between gas and liquid phases because
the differences in the optical path length
become negligible. To overcome these challenges, Jan
Eijkel and colleagues at the University of
Twente (The Netherlands) designed a
miniaturized Fabry–Pérot interferometer
with micromachined channels that had silver
mirrors embedded in both channel
walls.
