What is it about?

The transport of fluids across tortuous conduits is a challenge for several technological applications and biological scenarios. In many circumstances, this problem requires a detailed numerical approach that is very expensive in terms of time and computational power. This difficulty hampers the chance to reverse the question: can we exploit the shape of the conduit to induce some desired velocity profile?

Why is it important?

In this contribution we will show that it is possible to derive simplified models by which we can predict the transport properties of diverse membranes upon changing their shape. These models allow one to design micro and nanofludic devieces prerforming specific tasks.

Perspectives

This article contributed to the general perspective of understanding the dynamics and the transport of confined systems. In particular, the analytical approach pursued in this contributions highlights some novel scenarios in which the transport can be enhanced upon fine-tuning the shape of the conduits. These results highlght new routes to design micro and nano-fludiic devices.
