Nanotechnology for Medical Diagnostics and Treatment

Sunday June 1, 2008, 8:00 am - 6:00 pm, Boston, Massachusetts

Technology Focus

nanotechnology for medical imaging and therapy Nanotechnology has the potential to have a revolutionary impact on medical diagnosis and therapy. It is universally accepted that early detection of cancer is essential even before anatomic anomalies are visible. A major challenge in cancer diagnosis in the 21st century is to be able to determine the exact relationship between cancer biomarkers and the clinical pathology, as well as, to be able to non-invasively detect tumors at an early stage for maximum therapeutic benefit. For breast cancer, for instance, the goal of molecular imaging is to be able to accurately diagnose when the tumor mass has approximately 100-1000 cells, as opposed to the current techniques like mammography, which require more than a million cells for accurate clinical diagnosis.

nanotechnology early diagnosis and therapy of diseases In cancer therapy, targeting and localized delivery are the key challenges. To wage an effective war against cancer, we have to have the ability to selectively attack the cancer cells, while saving the normal tissue from excessive burdens of drug toxicity. However, because many anticancer drugs are designed to simply kill cancer cells, often in a semi-specific fashion, the distribution of anticancer drugs in healthy organs or tissues is especially undesirable due to the potential for severe side effects. Consequently, systemic application of these drugs often causes severe side effects in other tissues (e.g. bone marrow suppression, cardiomyopathy, neurotoxicity), which greatly limits the maximal allowable dose of the drug. In addition, rapid elimination and widespread distribution into non-targeted organs and tissues requires the administration of a drug in large quantities, which is often not economical and sometimes complicated due to non-specific toxicity. This vicious cycle of large doses and the concurrent toxicity is a major limitation of current cancer therapy. In many instances, it has been observed that the patient succumbs to the ill effects of the drug toxicity far earlier than the tumor burden.

Course Instructors

Dr. Amiji received his undergraduate degree in pharmacy from Northeastern University in 1988 and his PhD in pharmaceutics from Purdue University in 1992. His areas of specialization include polymeric biomaterials, advanced drug delivery systems, and nanomedical technologies.

Dr. Amiji’s research interests include synthesis of novel polymeric materials for medical and pharmaceutical applications; surface modification of cationic polymers by the complexation-interpenetration method to develop biocompatible materials; preparation and characterization of polymeric membranes and microcapsules with controlled permeability properties for medical and pharmaceutical applications; target-specific drug and vaccine delivery systems for gastrointestinal tract infections; localized delivery of cytotoxic and anti-angiogenic drugs for solid tumors in novel biodegradable polymeric nanoparticles intracellular delivery systems for drugs and genes using target-specific, long-circulating, biodegradable polymeric nanoparticles; gold and iron-gold core-shell nanoparticles for biosensing, imaging and delivery applications. His research has received sustained funding from the National Institutes of Health (NIH), National Science Foundation (NSF), foundations, and local industries.

Dr. Amiji is currently Professor and Associate Chairman of Pharmaceutical Sciences Department and Co-Director of Northeastern University Nanomedicine Education and Research Consortium (NERC). NERC oversees a doctoral training grant in Nanomedicine Science and Technology that was co-funded by the NIH and NSF. He has three published books, Applied Physical Pharmacy (McGraw-Hill, 2003), and Polymeric Gene Delivery: Principles and Applications (CRC Press, 2005), and Nanotechnology for Cancer Therapy (CRC Press, 2007) along with over 150 book chapters, peer-reviewed manuscripts, and abstract publications. Dr. Amiji has received a number of awards including the 2006 NSTI Award for Outstanding Contributions towards the Advancement of Nanotechnology, Microtechnology, and Biotechnology and 2007 American Association of Pharmaceutical Scientist’s Meritorious Manuscript Award.

Dr. Amiji has supervised research efforts of over 50 post-doctoral associates, doctoral and master’s level graduate students, and undergraduate honors students over the last 14 years. His teaching responsibilities are in Doctor of Pharmacy (Pharm.D.) program and graduate programs (M.S. and Ph.D.) in Pharmaceutical Sciences, Biotechnology, and Nanomedicine.

Srinivas Iyer, Ph.D., Technical Staff Member, Bioscience Division, Los Alamos National Laboratory, New Mexico, USA. Dr. Iyer has a Ph.D. from the University of Houston in biochemistry, with extensive experience in nano-bio technology development and commercialization. Previously, Dr. Iyer worked at the UNM Medical School in Albuquerque NM and he is presently at the Bioscience Division of the Los Alamos National Laboratory.
