How do fluorescent materials work
WebWhen hot materials become luminous and radiate light, a process called incandescence, the atoms of the material are in a high state of agitation. Of course, the atoms of every material are vibrating at room temperature … WebNow you can do fluorescence microscopy. Fluorescence microscopy gives you the advantage of better resolution by making various structures in the cells contrast better with their neighbors, as well as allowing you to collect images in more than one color.
