Characterizing Microgel Polymers and Nanostructures by Light Scattering

 

Presented Live: June 23, 2016

Speaker: Dr. Mark Spears Jr.

Microgels offer many promising attributes including tunable architectures, breadth of materials, and creative biological applications. These solvent-swollen, polymeric nanomaterials, ranging from tens of nanometers to several micrometers in size, are made of the same materials as their macroscopic counterparts, hydrogels. However, microgel behavior and properties are more challenging to predict and measure due to their dimensions.

In this webinar, we will discuss the analytical light scattering tools that are crucial to microgel characterization, illustrating how they determine the salient properties of microgels including response to temperature and solvent characteristics, core-shell structures, and degradation profiles.

Special thanks to Dr. L. Andrew Lyon and the group members of the Lyon laboratory at the Georgia Institute of Technology from which most of these data originate.

Wyatt Technology is the recognized leader in light scattering instrumentation and software for determining the absolute molar mass, size, charge and interactions of macromolecules and nanoparticles in solution.

Wyatt's line of multi-angle static light scattering products couple to size exclusion chromatography (SEC-MALS), field-flow fractionation (FFF-MALS), and stop-flow composition-gradient systems (CG-MALS). Our dynamic light scattering (DLS) products operate in traditional cuvette as well as on-line and automated, high-throughput modes. We also offer unique instruments for electrophoretic light scattering (MP-PALS), differential refractometry, and differential viscosity.
