To review:
The differences between transmission and scanning electron microscopy.
Introduction:
Microscopy is a technique that enables the resolution of the structures/objects that cannot be resolved by the human eye. There are various types of microscope and thus, microscopy. The basic principle is the same in all categories of microscopes but different approaches result in a significant difference of resolution power and variability in detection.
Electron microscopy is an advanced type of microscopy where electrons are used instead of an ordinary light source to bombard the specimen. The ten-thousand-fold higher resolution of electron beams helps better viewing of internal and external structures of bacterial species. The high resolution helps in a better understanding of many key cellular structures in detail. There are two types of electron microscopy – transmission and scanning electron microscopy. Differences between the two types are mentioned below:
