The highly intrincated nature of the interactions in nanochannels is a major challenge in order to rationalize and simulate transport in nanofluidic systems. The emerging consensus in the field is that a synergy between computational, theoretical, and new experimental approaches is required in the next few years.
This proposal follows the discussion meeting organized in Institut Henry Poincaré in May 2013 in the framework of the CFCAM node. A large part of the proposed participants were already attending to this meeting and have wished to be part of a CECAM workshop on the same thematics but with a larger scope in physics and biology.
On the experimental side, advancing our fundamental understanding of fluid and molecule transport on the smallest scales requires fluid and molecular dynamics to be ultimately characterized across an individual channel to avoid averaging over many pores. A major challenge for nanofluidics thus lies in building distinct and well-controlled nanochannels, amenable to the systematic exploration of their properties. There has been accordingly a intense effort to build new natural or artificial channels made either by transforming cyclic molecules, or based on the development of nanofabrication and heavy ions track etch techniques, such as focused ion beam and electron beam. Furthermore channels made of individual carbon or boron-nitride nanotubes were developed using nano-assembly techniques using nanotubes as nanoscale building blocks.
Nevertheless, many challenges are still ahead in this field. First, the fundamental physics of the transport in nanochannels are still poorly understood (force control during macromolecule translocation, explored energetic landscape, new fluid properties, …). Then, the studied channels are seen as passive objects and the idea of active biomimetic systems used to produce controlled nano-object still has to be developed.
