This Radical New DNA Microscope Reimagines the Cellular World
The new technique, dubbed DNA microscopy, uses only a pipette and some liquid reagents. Rather than monitoring photons, here the team relies on “bar codes” that chemically tag onto biomolecules. Like cell phone towers, the tags amplify, broadcasting their signals outward. An algorithm can then piece together the captured location data and transform those GPS-like digits into rainbow-colored photos.
