“…Particle swelling kinetics can be also estimated with chemo-electro-mechanical theoretical models, based on coupled nonlinear partial differential equations requiring moving boundary conditions 28 . On the other hand, MGs RI can be determined by combining measurements of the volume fraction of the MGs suspension, with RIs of both the suspension and the surrounding medium 29 , 30 . Specifically, the volume fraction can be derived experimentally from dynamic light scattering (DLS) and viscosimetry measurements 31 , while the RIs can be measured by means of an Abbe refractometer.…”

“…[ 16,17 ] The results were disparate and in apparent contradiction. While the first work reported a discontinuous transition, [ 16 ] the latter accounted for a smooth sigmoidal one, [ 17 ] but being unspecified if the sigmoidal behavior was obtained by averaging results over several microgels. Moreover, the same authors found a rather discontinuous transition for pH‐responsive microgels upon pH changes, [ 18 ] so the available results are inconclusive.…”

“…[8][9][10] Only recently, some works dealt with the characterization of the VPTT transition of thermoresponsive microgels by optical tweezers, that is, measuring properties on a one-microgel-at-a-time basis while externally heated. [16,17] The results were disparate and in apparent contradiction. While the first work reported a discontinuous transition, [16] the latter accounted for a smooth sigmoidal one, [17] but being unspecified if the sigmoidal behavior was obtained by averaging results over several microgels.…”
