The three projects utilized polymer physics theories to investigate polymer aggregation mechanics. Dynamic light scattering (DLS), static light scattering (SLS) and small angle light scattering (SALS) were the primary characterization tools. The goal of the first project was to study the aggregation of bovine βL-crystallin and apply that knowledge towards cataract formation, which is caused by aggregation of the crystallins. The first series of experiments characterized the kinetics of α-crystallin and βL-crystallin in water at room temperature. α-crystallin’s equilibrium hydrodynamic radius value was kinetically independent. βL-crystallin formed an aggregate with an Rh that was kinetically dependent. The packing structure ...
