Query: Non-destructive Imaging of Individual Bio-Molecules   Radiation damage is considered to be the major problem that still prevents
imaging an individual biological molecule for structural analysis. So far, all
known mapping techniques using sufficient short wave-length radiation, be it
X-rays or high energy electrons, circumvent this problem by averaging over many
molecules. Averaging, however, leaves conformational details uncovered. Even
the anticipated use of ultra-short but extremely bright X-ray bursts of a Free
Electron Laser shall afford averaging over 10^6 molecules to arrive at atomic
resolution. Here we present direct experimental evidence for non-destructive
imaging of individual DNA molecules. In fact, we show that DNA withstands
coherent low energy electron radiation with deBroglie wavelength in the
Angstrom regime despite a vast dose of 10^8 electrons/nm^2 accumulated over
more than one hour.
