Light-emitting bioprobe fits in a single cell
Date:2/13/2013

he cell interior.

In one finding that the authors describe as stunning, they loaded their nanobeams into cells and watched as the cells grew, migrated around the research environment and reproduced. Each time a cell divided, one of the daughter cells inherited the nanobeam from the parent and the beam continued to function as expected.

This inheritability frees researchers to study living cells over long periods of time, a research advantage not possible with existing detection techniques, which require cells be either dead or fixed in place.

"Our nanoscale probes can reside in cells for long periods of time, potentially providing sensor feedback or giving control signals to the cells down the road," said Shambat. "We tracked one cell for eight days. That's a long time for a single-cell study."
