Engineering of new biodegradable materials with properties of interest for their potential utilization as drug carriers or drug delivery systems in biomedical and pharmaceutical fields. Design and testing of a new nanopolymer anti-cancer molecular delivery system that specifically delivers drugs to the tumor cells using a targeting monoclonal antibody. This novel system releases tumor growth inhibiting agents specifically into cancer cells without affecting normal surrounding cells.
Discovery of brain tumor genes/proteins important for tumor angiogenesis. Developed nanotechnology to block the synthesis of tumor-specific proteins responsible for angiogenesis. Initiated clinical program at Cedars-Sinai for prognostic and diagnostic evaluation of human brain tumor angiogenic markers.
Current investigations include:
The drug delivery system passing through blood brain barrier to deliver drugs to brain tumors and having the ability to block several cancer-specific tumor markers at the same time by using biodegradable nanoconjugate for brain and breast tumors. Cancer specific drug targeting.
