Table 1. DLS and viscometry data.
Summary of results from DLS and viscometry studies for cross-linker-free and microgels cross-linked with varying amounts of PEG-DA. The symbol RH and k represent the hydrodynamic radius of the particles and the shift factor in the Batchelor equation (Eq 1), respectively.
