Abstract

Abstract : Here, we apply a recently developed superresolution fluorescence microscopy approach using freely diffusing dye molecules to study the network structure of non-NIPAM based microgels. Use of different monomers leads to differences in network density. Abstract : In a recent publication [Bergmann et al. Phys. Chem. Chem. Phys., 2018, 20, 5074–5083] we presented a method which enables to investigate the morphology of microgels by superresolution fluorescence microscopy. Here, this method is applied to three microgel species, based on N -isopropylmethacrylamide (NIPMAM), N-n -propylacrylamide (NNPAM) and N-n -propylmethacrylamide (NNPMAM)) with 5, 7.5 and 10 mol% cross-linker, respectively. Super-resolution microscopy reveals differences of the network morphology of the synthesized particles showing the importance of the monomer structure.
