Researchers Use Dots to Light Up Tumor Cells

JAMA. 2004;292(16):1944-1945. doi:10.1001/jama.292.16.1944

Much like wildlife biologists studying the comings and goings of animals in nature with devices like radiocollars, cancer investigators would relish in the opportunity to track malignant cells and watch them in action. If they could observe how tumor cells grow and spread, they might be able to come up with effective treatment strategies.

Now researchers are able to see the minute-by-minute activities of cancer cells, thanks to a new technology that uses fluorescent inorganic nanocrystals that glow under UV light. Two new studies highlight the utility of these tiny particles, called quantum dots.
