(biophysics) At the scale or level of Ångström units, used especially to indicate an image being shown at a very high resolution (atomic level), and to show dimensional relativity of atoms (or molecules).
Biological structures on an atomic or Ångström scale can now be viewed using advanced microscopes. DNA-protein complexes can now be directly visualized. Being able to see at a very high resolution is important to derive precise information.
