Zusammenfassung der Ressource
Microscopy
- Light microscopy
- up to x1500
- 200nm
- visualize cells+major
intracellular organelles
- 2D but sometimes can be 3D
- live specimen, cell
movement+motility
- Low
- Transmission electron
microscopy
- up to x200 000
- 0.2nm
- details of intracellular organelles
- 2D
- electrons are transmitted through the
speciman, so it has to be dead+fixed
- high
- Scanning electron
microscopy
- wide range (from x10 to x100 000)
- 1nm
- image of surfaces
- 3D
- electrons are reflected
back from the surface of
the speciman
- high
- Microscopys
- Magnification
- Resolution
- what is it used for?
- Dimensions
- Speciman
- Cost
