Unmatched visualization and measurement of nanoparticles

Analyzing nanoparticles such as colloids and proteins is inherently challenging. These particles are too small to image with visible light and must be imaged by laborious electron or scanning microscopy. Dynamic light scattering and laser diffraction have been successfully used to determine particle size and size distribution. These techniques are fast and accurate for certain samples, however, as they are ensemble techniques, high resolution distribution information cannot be obtained.
