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?
Study of nanofluidic phenomena can occur indirectly via interface studies, nanoporous
material, or nanometer-scale microdevices. Click

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.
