There are numerous reports in the literature where DLS has been used to follow the collapse of the colloidal microgel particles across the VPT [45,47]. By comparing the hydro-dynamic diameter before and after the transition it is possible to determine the swelling ratio of the microgel. 

As with other physico-chemical properties of colloidal microgels the rheological behaviour of dispersions distinctly changes in response to environmental stimuli. At low temperatures the viscoelastic properties of poly(NIPAM) microgels change dramatically with temperature [89, 90]. At low temperatures poly(NIPAM) dispersions display elastic-type behaviour as... 

Colloidal microgels have attracted considerable attention over the past 10-15 years and many attempts have been made to try to better imderstand the correlation between their structure and resultant properties. As microgels can be prepared in a variety of different...
