Quantum dots boost tissue imaging

June 2, 2003 | Source: New Scientist

An ultra-high resolution technique for imaging living tissue can provide a thousand-fold increase in resolution, thanks to the addition of tiny nanocrystals called quantum dots. Researchers ultimately hope to use the technique to probe ovarian tumors and other types of cancer deep in the body.

Specific cells, such as cancer cells, can be targeted by adding antibodies to quantum dots, which then act as homing devices.
