Aquaporin Nanochannel: Single-File Water Transport & Ion Exclusion

3D biomimetic nanochannel simulator: watch water molecules cross a sub-nanometer pore single file while a Born-type dielectric-exclusion model shows why ions and protons are almost completely blocked, exactly as in a real aquaporin channel.

This simulator visualizes the nanobiomimetic mechanism behind aquaporin water channels — the sub-nanometer protein pores that let cells move billions of water molecules per second across their membrane while almost completely excluding ions and protons. A cylindrical channel connects two reservoirs; water molecules cross in a strict single file, unable to pass one another, with dipole arrows that flip orientation at the channel's midpoint to show the bipolar arrangement that breaks the hydrogen-bond wire protons need to hop through. Na⁺ and Cl⁻ ions periodically attempt the pore and are rejected according to a Born-type dielectric-exclusion model driven by the pore-radius control, matching how real selectivity filters trade pore size for ion rejection. Adjust the driving pressure, electrolyte concentration and temperature and watch the live water-flux and ion-rejection readouts respond in real time.

⚙ Under the hood

A 3D biomimetic nanochannel simulator: water molecules cross a sub-nanometer pore in strict single file while a Born-type dielectric-exclusion model shows why ions and protons are almost completely blocked, mirroring how real aquaporin channels achieve both huge water flux and near-perfect selectivity.
