Remote Drug Loading — Ammonium-Sulfate Liposome Gradient

Interactive 3D simulator of remote (active) liposomal drug loading: a transmembrane ammonium-sulfate pH gradient pulls a weakly-basic drug across the lipid bilayer and traps it inside as the interior acidifies, the mechanism behind clinical drugs like liposomal doxorubicin.

This simulator renders a single liposome in cutaway: a lipid-bilayer shell holding a concentrated ammonium-sulfate interior, bathed in an external buffer carrying a weakly basic drug. Neutral drug molecules diffuse across the membrane; as escaping NH₃ acidifies the interior, crossed molecules protonate and become trapped, building up as a dense core. Adjust the ammonium load, drug dose and temperature and watch the loading-efficiency curve plateau exactly where the chemistry says it should — this is the remote-loading mechanism used to manufacture liposomal doxorubicin and similar clinical nanomedicines.
