Ion channels are narrow passageways that play a pivotal role in many biological processes. To model how ions move through these tight spaces, pores need to be fabricated at very small length scales.

The discovery that tissues use electricity to expel unhealthy cells is part of a surge of renewed interest in the currents flowing through our bodies. We’re used to thinking of the brain as an ...

Daniel Hallinan Jr. works with perfluorosulfonic acid (PFSA) polymers in his lab in the Aero-Propulsion Mechatronics & Energy building at the FAMU-FSU College of Engineering. FAMU-FSU College of ...

Researchers shrink solid-state nanopores to sub-nm size via voltage-driven precipitation/dissolution, creating tunable pores that mimic ion channels for studying confined ion transport.
