- Solid particles at the micron size range are fully characterized by Automated Optical Microscopy and an image analysis software to obtain statistical distributions of any morphological parameter: Circular equivalent and Feret diameter (Particle Size Distribution), circularity, aspect ratio, roughness, amongst others.
- Solid nanoparticles are analysed, after appropriate sample preparation, by Scanning Electron Microscopy (SEM), to obtain high-resolution images which can be further processed for quantitative analysis (ImageJ).
- Nanoparticles in colloidal formulations are visualized in their native state by Cryogenic transmission electron microscopy (cryo-TEM), and further analysed by image analysis software to lead to quantitative analysis of their morphological parameters.
