  • Self-assembling bis-urea compounds for drug delivery
    Patent number: 9084735
    Abstract: 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.
    Type: Grant
    Filed: August 1, 2013
    Date of Patent: July 21, 2015
    Assignees: International Business Machines Corporation, Agency For Science, Technology And Research
    Inventors: Daniel J. Coady, Richard A. Dipietro, Amanda C. Engler, James L. Hedrick, Shao Qiong Liu, Jed W. Pitera, Shrinivas Venkataraman, Yi Yan Yang
