A new technique creates images of DNA bundles (above) with nanometer-scale resolution by using light to sense molecular vibrations. It might ultimately be able to map out the components in a single DNA molecule. Image Credit: Phys. Rev. Lett. 92, 220801 (2004)
Born of the marriage of two cutting edge techniques, a new method can image bundles of DNA strands by sensing vibrations within the molecules. This method can detect objects only dozens of atoms wide. It might someday enable researchers to map out the constituents of individual biomolecules.
