Intracellular microlasers could allow precise labeling of a trillion individual cells


"The narrow-band spectrum of light emitted by these intracellular lasers would allow us to label thousands - in principal up to a trillion - of cells individually, and the very specific wavelengths emitted by these microlasers also would allow us to measure small changes happening within a cell with much greater sensitivity than is possible with broadband fluorescence."

The investigators calculated that it would be possible to tag individual cells with more than a trillion different laser signatures, a number that matches the estimated number of cells in the human body.
