In this episode, nanotechnology is promoted as an enabling technology. Nano devices can provide a way to automate routine laboratory tests. They can deliver active treatment directly to affected cells and that means fewer side effects and increased efficiency. Dr. Chad Mirkin is the Director of the International Institute for Nanotechnology at Northwestern University and he shows how the new diagnostic devices allow doctors to do multiple tests with a single sample.At the Dana Farber Cancer Institute at Harvard, we learn how nano-devices can be used to destroy specific cancer cells. Through nanotechnology the practice of medicine is evolving from treating disease and illness to a practice that is predictive, personalized and preemptive. There is a medical future where permanent nano-devices can roam the body to monitor for, provide early diagnosis of, and take action against diseases.Nanotechnology is a powerful tool for advancing tissue engineering and stem cell therapy. Significant results have been obtained in creating artificial functioning interfaces between nerve fibers and electronic contact electrodes. This open the way to control prosthetics and all kinds of implants.
