摘要：
Cationic, anionic, and/or zwitterionic bis-urea compounds self-assemble by non-covalent interactions in aqueous solution to form high aspect ratio nanofibers. The nanofibers reversibly bind drugs by non-covalent interactions, forming drug compositions for exhibiting sustained release of the drug.
