Amino Acid Directed Helical Assemblies of Natural Berberine for Chirality‐Dependent Photodynamic Antibacterial Therapy

open access: yesAdvanced Science, Volume 13, Issue 3, 14 January 2026.
Helical nanostructures co‐assembled from berberine (BBR) and Fmoc‐Y display supramolecular‐chirality‐dependent photodynamic antibacterial activity. The molecular chirality of Fmoc‐Y organizes achiral BBR into chiral nanofibers, where supramolecular handedness controls bacterial surface adsorption, membrane penetration, intracellular BBR delivery, and ...
