Direct determination of particle morphology is a critical aspect of nanoparticle characterization. Typical analyses include particle size distribution, shape, and overall appearance of particles in a sample, and can include quantitative analysis of circularity.
All of these measurements can be obtained in one cryo-TEM or negative stain imaging study, with a small amount of sample.
