Herein we report, for the first time, a straightforward approach for the  synthesis of polyampholyte Janus-like microgels, where ionizable groups  of opposite charge are located on different sides of the colloidal  network. Our synthesis approach is based on the controlled self-assembly  of growing polyelectrolyte microgel precursors during the precipitation  polymerization process. We confirmed the morphology of polyampholyte  Janus-like microgels and demonstrate that they are capable of responding  quickly to changes in both pH and temperature in aqueous solutions.<\/p>\n\n\n\n<p><em>Wenjing Xu, Andrey Rudov, Alex Oppermann, Sarah Wypysek, Michael Kather, Ricarda Schroeder, Walter Richtering, Igor I.
