Nanoscale Quantum Dots Hold Promise for Cancer Applications

Elia T. Ben-Ari

The first 150 words of the full text of this article appear below.

Nanotechnology, a field few people had heard of a decade ago, is now the focus of a $750 million-plus U.S. government program, not to mention the subject of Michael Crichton’s latest bestseller. Scientists in this multidisciplinary field are creating new materials and devices with dimensions of 1 to 100 nanometers (billionths of a meter) and exploring a host of potential uses for these nanoscale objects.

Among the nanomaterials in the spotlight are fluorescent semiconductor nanocrystals, also known as quantum dots—clusters of a few hundred to a few thousand atoms that emit light in rainbow hues. When quantum dots were first produced in the early 1980s, researchers envisioned their use in computing, optics, and electronics. But the first practical applications of these tiny bits of semiconductor may actually occur in biology and medicine, where they show promise as an alternative to fluorescent organic dyes and proteins for labeling and imaging . . .
