Project CIAICO/2022/247

Objective

We employ biomimetic nanopores to achieve a qualitative understanding of the instructive bioelectric signaling in multicellular ensembles.

To this end, we will study both theoretically and experimentally the ionic transport through conical nanopores with applications in sensing and actuating such as nanofluidic memristors that can be used as a simplified model of biological synapsis.

Our methods are based in experiments and theoretical simulations. We want to acquire a better understanding of the basic physico-chemical aspects of the transport properties of nanopores.
