Non-Blinking Quantum Dots

Quantum dots are cool. They're bright, small, and they don't photobleach. The problem: they blink, and the "off" state can last a long time. Certain preparations can reduce the blinking, but personally my luck with this has been pretty middling. Now, apparently, a group of researchers has produced non-blinking quantum dots. All I can say is: wow! And: when can I buy them?
