Nanoparticle lights up at the site of cancer

Abstract:
A new nanoparticle can multitask as a drug courier and a delivery reporter by glowing when it dumps its cargo inside tumour cells. The technique could allow doctors to see exactly which cells have successfully received a drug - if it gets approval for use in humans.

"Quantum dots" are reflective crystals about 1000th of the width of a human hair. They show much promise as medicinal tools due to their extremely bright fluorescence and the ability to carry other molecules on their surface. Until now, however, quantum dots have been continually fluorescent, regardless of which tissue they may have reached, or what job they may have done.
