Which Type of Microscopy is Particularly Useful to Study the Surfaces

Question

Which type of microscopy is particularly useful to study the surfaces of live bacteria?
A) atomic force
B) scanning electron
C) transmission electron
D) dark-field
E) bright-field

Accepted Answer

Atomic force microscopy (AFM) is particularly useful for studying the surfaces of live bacteria because it can image surfaces in their natural state, without the need for staining or fixation, and can operate in a liquid environment, allowing for the observation of live specimens.
