UCF nanotechnology may speed up drug testing
Date:12/19/2011

Testing the effectiveness of new pharmaceuticals may get faster thanks to a new technique incorporating quantum dots developed at the University of Central Florida.

Some drug testing can take a decade or more, but UCF associate professor Swadeshmukul Santra and his team have created an electronic quantum dots (Qdots) probe that "lights up" when a drug it is delivering attaches to cancer cells. The research appears online in this month's Biomaterials. http://www.sciencedirect.com/science/article/pii/S0142961211012841#FCANote

A researcher can use a microscope to see where and how much of the drug has been delivered because the probe emits a reddish color under special lighting or via MRI because of its optical and magnetic components.

As the drug testing continues, images can be taken over and over without any loss of optical or MRI signal. Researchers can then measure the size of the tumor and number of cancer cells that "light up" compared with the original untreated tumor.

This provides a way to determine whether the drug is doing what it is supposed to be doing in the targeted areas. The technique is much easier than the current process of removing treated cancer tumors and weighing them at regular intervals to determine the drug's efficiency in an animal.

"Many people in my area have been studying this approach for years," Santra said. "But we have now moved it into a live cell, not just in test tubes."

Sudiptal Seal, the director of UCF's NanoScience Technology Center and nanoscience scientist believes Santra's research is significant.

"This is indeed a major breakthrough in Qdot research," Seal said. "This new diagnostic tool will certainly impact the field of nanomedicine."

Santra and his team used semiconductor Qdots to create the probe. Because of their small size and crystal-like struc
