Research Interest

Rational design of biomedical polymers to target drugs and diagnostic agents to diseased sites in the body.
Dr. David and her coworkers develop targeted drug delivery platforms, including polymer-drug conjugates and self-assembled polymeric micelles, equipped with targeting ligands specific for endothelial and cancer cells markers, to deliver anticancer drugs and oligonucleotides as well as Near Infrared fluorescent (NIRF) molecules into tumor vascular endothelial and cancer cells at the tumor microenvironment. Dr David further utilizes activated cell penetrating peptide (aCPP) sequences to trigger drug penetration into cancer cells. Such targeted polymer have been found useful for (a) delivering drugs to treat diseases without toxic side-effects; (b) targeting imaging agents into solid tumors for diagnostic applications; and (c) deliver DNA to antigen-presenting dendritic cells to enhanced antigen-specific immune responses for the treatment of a wide range of diseases including cancer and inflammation.
