Testing the effectiveness of new pharmaceuticals may get faster thanks to a new technique incorporating quantum dots developed at the University of Central Florida.<\/p>\n

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 \u201clights up\u201d when a drug it is delivering attaches to cancer cells. The research appearsonline in this month\u2019s Biomaterials. <\/a><\/p>\n

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.<\/p>\n

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 \u201clight up\u201d compared with the original untreated tumor.<\/p>\n

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\u2019s efficiency in an animal.<\/p>\n

\u201cMany people in my area have been studying this approach for years,\u201d Santra said. \u201cBut we have now moved it into a live cell, not just in test tubes.\u201d
\nSudiptal Seal, the director of UCF\u2019s NanoScience Technology Center and nanoscience scientist believes Santra\u2019s research is significant.<\/p>\n

\u201cThis is indeed a major breakthrough in Qdot research,\u201d Seal said. \u201cThis new diagnostic tool will certainly impact the field of nanomedicine.\u201d<\/p>\n

Santra and his team used semiconductor Qdots to create the probe. Because of their small size and crystal-like structure, Qdots display unique optical and electronic properties when they get excited. These unique properties make them ideal for sustained and reliable imaging with special lights.<\/p>\n

For this research funded by the National Science Foundation and National Institutes of Health, the UCF-led team used a superparamagnetic iron oxide nanoparticle core decorated with satellite CdS:Mn\/ZnS Qdots which carried the cancer-fighting agent STAT3 inhibitor. The Qdot optical signal turned on when the probe bonded with the cancer cells.<\/p>\n

\u201cThe potential applications for drug testing specifically for cancer research are immediate,\u201d Santra said.<\/p>\n","protected":false},"excerpt":{"rendered":"
