Description
Animation explaining how a nanopore sensor can identify individual molecules from current changes as they pass through a tiny opening.

Context

Nanopore sensors identify molecules by measuring how a molecule changes electrical current as it passes through a tiny pore. The research focused on how long molecules stay in the pore, because the signal needs enough time to be measured clearly.

Approach

The animation shows the pore, the molecule, and the changing current signal together. It slows the process down so the viewer can connect molecular motion with the measured electrical response.
