For sub-micron and even sub-nanometre resolution of various sample types, the transmission electron microscope (TEM) is extensively used for both biological and chemical studies of cell sections and novel compounds.
The scanning electron microscope (SEM) is used for morphological studies of even more varied sample types. These vary from single cells to light bulb elements.
There is a range of peripheral equipment.
Our TEM is an FEI Tecnai 12 G2 fitted with a CCD camera for ease and speed of use. The resolution is around 0.4nm and capable of discriminating small variation in size of nm particles. The TEM is also used to study protein localisation and co-localisation with gold particles. Our technician has all the necessary experience to prepare samples of varying kinds (plant and animal sections, immuno-labelling of cryosections, nanoparticles samples).
The SEM is ideal for detailed morphological studies which are beyond the resolution of light microscopes. Samples vary from the monocultured cell to plant leaves, light bulb filaments through to metal chips.
