Direct imaging and spectroscopic characterization of stimulus-responsive microgels.
Scanning transmission X-ray microscopy has been employed to visualize pH-responsive acid-swellable microgel particles directly in their swollen state in aqueous acidic solution. Moreover, NEXAFS studies confirm that the nitrogen atoms of these cationic microgel particles are completely protonated at low pH.
