Nanofluidics hold a promising future for developing novel molecular manipulation systems such as biomolecule sieves, which are essential in the context of the micro total analysis system. Unlike conventional nanoporous molecular filters or sieves, nanofluidic filters can be carefully designed to have a regular structure that can be used to manipulate biomolecules and other particles in a well-defined way. Implications of such devices are significant, and could lead to a new concept for biomolecule analysis and separation. Fluidic properties and molecular diffusion at the nanoscale is quite different from that of micro or macroscale, and nanofluidic devices can be designed to exploit these novel properties to provide solutions to various engineering problems. However, further basic and applied research should be done to investigate the science of fluid and molecules in fluid at the nanoscale.
