Nanoparticle Characterisation: Size and Stability
Nanoparticles have shown immense potential in array of industrial sectors and hence the characterisation of their intrinsic properties viz., size, charge and stability are of utmost importance. Light scattering offers a quick, easy and non-invasive technique for these measurements. On one hand, Dynamic Light Scattering (DLS) measures the average size and polydispersity index of nanoparticle emulsions; the Electrophoretic Light Scattering (ELS) assesses the zeta potential measurement to govern their stability.
In this webinar we will learn about the basics of these light scattering approaches including DLS and ELS techniques. Besides, glimpses will also be shared about the data interpretation and validity of methods for these techniques and their use in different industrial applications.
- Role of nanoparticles in daily life and requirement of their characterisation
- Nanoparticle size determination using Dynamic light scattering technique
- Zeta potential determination for assessing the stability of nano-emulsions
- Common examples for Litesizer 500 applications
