Nanotechnology In Medical Application

One area of nanotechnology application that holds the promise of providing great benefits for society in the future is in the realm of medicine. Nanotechnology is already being used as the basis for new, more effective drug delivery systems and is in early stage development as scaffolding in nerve regeneration research. Moreover, the National Cancer Institute has created the Alliance for Nanotechnology in Cancer in the hope that investments in this branch of nanomedicine could lead to breakthroughs in terms of detecting, diagnosing, and treating various forms of cancer.

Nanotechnology is also making possible the stimulation of the body’s own mechanisms to successfully repair diseased or damaged tissues, replacing the need for transplants and artificial organs. In the foreseeable future, nanotechnology as applied to medicine, will lead to advancement in remote monitoring and care, where a patient may be treated at home - a less expensive option, and one that is more conducive to a successful medical outcome than treatment in a surgery or hospital.

Apply Nanotechnology To Prostate Cancer Therapy

A team of scientists from the UNC Lineberger Comprehensive Cancer Center has received one of 10 creativity awards from the Prostate Cancer Foundation for advanced prostate cancer research. The one-year awards are designed to support innovative ideas that have the potential to achieve breakthroughs for the detection and treatment of prostate cancer.

Their work involves nanoscale fabrication technology that may provide new modeling capabilities and therapies to arrest lethal prostate cancer progression.

The Lineberger team members include Shelton Earp, M.D., professor of medicine and pharmacology and center director; Joseph DeSimone, Ph.D., Chancellor’s Eminent Professor of Chemistry in the UNC College of Arts and Sciences; and Young Whang, M.D., Ph.D., associate professor of medicine in the UNC School of Medicine.

Earp, Whang and colleagues discovered that a signaling molecule named Ack1 can cause low-grade, tumorigenic prostate cancer cells to become androgen-independent, the state that results in advanced human prostate cancer. Other UNC scientists, led by DeSimone, have developed a nanoparticle drug delivery technology.

The scientists plan to model widely spread prostate cancer using Ack1-driven prostate cancer cells to test whether DeSimone’s nanoparticles can be targeted to the cancer, both to detect its location and to carry effective treatment that is not toxic to the rest of the body.
