In transmission electron microscopy, electron opacity is greatly enhanced by treating the specimen with
-
- ferrous ammonium sulfate
- uranium acetate
- sodium chloride
- basic fuchsin
Correct Option: B
In transmission electron microscope, to increase the electron opacity samples are impregnated with heavy metals such as uranyl acetate. Uranyl acetate is a water-soluble uranium compound and is often used as stains in electron microscopy.
