      abstract     = {Thermoresponsive polymer gels exhibit pronounced swelling
                      and deswelling upon changes in temperature, accompanied by
                      dynamic concentration fluctuations that have been
                      interpreted as critical opalescence. These fluctuations span
                      lengthscales similar to that of static structures in the
                      gels, such as the gel polymer-network meshsize (1–10 nm)
                      and static polymer-network crosslinking inhomogeneities
                      (10–1000 nm). To systematically investigate this overlay,
                      we use droplet-based microfluidics and fabricate
                      submillimeter-sized gel particles with varying static
                      heterogeneity, as revealed on a molecular scale by proton
                      NMR. When these microgels are probed by small-angle neutron
                      scattering, the detection of dynamic fluctuations during the
                      volume phase transitions is strongly perturbed by the
                      co-existing static inhomogeneity. Depending of the type of
                      data analysis employed, the temperature-dependent evolution
                      of the correlation length associated to the dynamic
                      fluctuations does or does not agree with predictions by the
                      critical scaling theory. Only the most homogeneous sample of
                      this study, prepared by controlled polymer crosslinking in
                      droplet microfluidics, shows a diverging correlation length
                      in agreement to the critical scaling theory independent of
                      the specific approach of data analysis. These findings
                      suggest that care must be taken about polymer-network
                      heterogeneity when gel volume phase transitions are
                      evaluated as critical phenomena.},
