Probe Emits Light in Living, Unharmed Cells

Facebook Twitter LinkedIn Email Comments
STANFORD, Calif., Feb. 14, 2013 — A new class of light-emitting probes small enough to be injected into individual cells without harming them could provide new ways of exploring the dynamics of living cells. The Stanford University engineers are the first to demonstrate that sophisticated engineered light resonators can be inserted inside cells without damaging them. Their nanobeam — only a few microns in length and just a few hundred nanometers in width and thickness — looks similar to a piece from an old erector set with holes through the beams that act like a nanoscale hall of mirrors, focusing and...Read full article
