PittCon: Size, Molecular Weight and Zeta Potential Characterization of Nanomaterials

The objectives of this course are to discuss Dynamic Light Scattering, Nanoparticle Tracking Analysis, Molecular Weight and zeta potential methods. DLS and NTA are versatile and non-destructive measurement techniques that are ideally suited as a metrology of choice for size, stability and identification of nanomaterial, protein molecules, aggregates and emulsions or suspensions in solution. We will also discuss electrophoretic mobility measurements and the importance of zeta potential in understanding interfacial behavior and the formulation of multi- component products. We will discuss; DLS and NTA, differences between these sizing methods, review theory, provide useful tips for sample preparation and analysis of measurement results, molecular weight, introduce micro-rheology and zeta potential.
