Researchers: Molecular forklifts overcome obstacle to 'smart dust'
Date:1/18/2009

mechanism derived from a natural system into an artificial microsensor," he wrote in an e-mail. "The authors show how adding the ability to move around in an autonomous fashion can dramatically improve the performance of the microsensor."

Hess emphasized that the research results represent only the initial of many steps toward smart dust. Among other challenges, the molecular forklifts need to be sped up, producing results in seconds or minutes rather than hours. But, he said, the process suggests that there are promising, alternative to traditional lab-on-a-chip assays.

"Right now, this is light years away from competing with any assay," he said. "But, it is a completely different way of doing it."
