Abstract: Abstract The electrophoretic mobility of poly(N-isopropylacrylamide) and poly(N-isopropylacrylamide-co-acrylic acid) copolymer particles, as well as different core-shell microgel particles (neutral core with charged shell and charged core with neutral shell) was investigated as function of microgel swelling. The swelling of the microgels were varied with increasing the temperature. To interpret the experimental results, we used scaling arguments to show that due to the strong hydrodynamic interactions the inner part of the microgel particles ar...
