Researchers have found a new way to produce images of living cells' interiors without disturbing their biochemistry. The technique, described in the 17 May issue of Physical Review Letters, uses lasers to excite certain chemical bonds within the cells to emit light. Experts say it may be a useful addition to existing imaging techniques.
