What are microscopes used for today?
They are used in cytopathology (looking at pap smears and other specimens from any body site, smeared on glass slides, to search for cancer, precancerous cells, organisms) and pathology (looking at pieces of body parts that have been sliced very thinly and placed on glass slides and stained to search for disease processes). Some scopes are now even computer controlled for use in cytology/cytopathology. Check out Cytyc.com.
