Dr. Knight is investigating the use of biocompatible nanoparticles as in vivo diagnostic imaging agents. The nanoparticles are targeted to molecular markers of disease and are detectable by imaging methods such as magnetic resonance imaging. It is hoped that disease-specific nanoparticles can be used to carry therapeutic agents as well as being used to provide initial diagnosis and monitoring of the progress of therapy. This work is an outgrowth of Dr. Knight’s work on physiologic imaging using radiotracers.

Why Is Small So Big?
Nanotechnology deals with products and processes that are measured in almost unbelievably small increments called “nanometers”—one billionth of a meter.
At the nanoscale, materials differ from larger objects in their physical, chemical and biological properties; therefore, they lend themselves to new and improved materials, systems and devices. Nanotechnology is behind the development of such diverse advancements as:
- Drug Delivery
- Biofiltration and Separation sciences
- Improved coatings for medical devices
Thanks to rapid advances in this exciting new field, we now have the tools and talents to manipulate materials on the molecular scale—a technology literally changing the world as we know it.
