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.

脲化合物在
水溶液中通过非共价相互作用自组装成高纵横比纳米纤维。这些纳米纤维通过非共价相互作用可逆地结合药物,形成药物组合物,以实现药物的持续释放。
