The Scanning Electron Microscope (SEM) generates images that resemble three-dimensional structures. Like TEM, it uses electrons to generate an image, but it scans through the surface of the material, generating secondary electrons that are then detected by a sensor (from cells to whole organisms can be scanned). SEM provides a great depth of field and allows the operator to observe the fine details of the morphology and surface of the samples. Multiple SEM systems are available for users to train on or for image acquisition to be carried out by experts. This technique enables the reconstruction and analysis of samples with nanometer resolution.


– Cell morphology
