A. Yes, but not in detail. âMany scientists use electron, scanning tunneling and atomic force microscopes to view individual DNA molecules,â said Michael W. Davidson, curator of the National High Magnetic Field Laboratory at Florida State University.
Electron microscopy (EM) is a technique for obtaining high resolution images of biological and non-biological specimens.It is used in biomedical research to investigate the detailed structure of tissues, cells, organelles and macromolecular complexes.lectron microscopy is used in conjunction with a variety of ancillary techniques (e.g. thin sectioning, immuno-labeling, negative staining) to answer specific questions. EM images provide key information on the structural basis of cell function and of cell disease.
