Nanofluidic Transport
Nanofluidic phenomena are characterized by length scales ranging roughly between 1 nm and 100 nm. At these length scales, a number of novel questions arise, which include the following:
  • how exactly does the no-slip condition apply to fluid flow?
  • how are fluid constitutive properties (viscosity, dielectric constant) affected by the presence of the wall?
  • how is ion transport affected inside electrical double layers?
  • how can the enormous electrical fields inside electrical double layers be used to advantage?
  • how can small channels be used to better manipulate and control macromolecules, such as proteins and DNA?
Study of nanofluidic phenomena can occur indirectly via interface studies, nanoporous material, or nanometer-scale microdevices. Click here for a recent Analytical Chemistry article on nanofluidics. We are currently exploring the use of nanoscale structures for DEP manipulation of nanoparticles and macromolecules, investigating interfacial phenomena within nanometers of surfaces, and exploring transport properties in nanoporous material used for sample dialysis or tissue engineering.
