Synthesis and Characterization of Amphiphilic Dendron Coils – Potential Nanomicelle Precursors Jeromy T. Bentley University of Illinois at Chicago RET Fellow Department of Biopharmaceutical Sciences Advisor: Dr. Seungpyo Hong Mentor: Ryan Pearson July 28, 2011
Summer Plan • Synthesize functionalized lipophilic polymer “coil” • Conjugate hydrophilic PEGylateddendron to lipophilic polymer coil to create amphiphilicdendron coil and induce self-assembled structure formation • Characterize synthesized amphiphilicdendron coils by 1H NMR • Characterize self-assembled micelles by TEM.
Background - Dendron Coils • Dendron Coils – linear polymer that is dendronized at one end. Amphiphilicity can be engineered to allow for self-assembly. • Nanomicelles – very small self-assembled structure (<200 nm) capable of being used in drug delivery
Dendron • Dendron – portion of a dendrimer (lots of branching) dendron dendrimer
