Contructs of multilayer nanoparticles require knowledge of the particle size and composition at all stages of manufacturing. Release and toxicity of nanoparticles is also a concern. Methods such as electron microscopy, dynamic light scattering, Fraunhofer scattering and single particle detection are methods largely employed to study nanoparticle structures. Nanoparticle tracking analysis is a new approach as an alternative to light scattering method. This method allows a wide range of particles to be analysed in a wide range of solvents. The method is robust and at low cost reliable. Further the method allows results by far better in terms of particle size distribution when compared with photon correlation spectroscopy.
