Stimulus-responsive membrane: (a) temperature-triggering, comparison of nanogel particle size in suspension (blue data, right y-axis) and differential flux of sodium fluorescein through the nanogel-loaded membranes (red data, left y-axis) as a function of temperature; (b) magnetic triggering, temperature profile in the sample chamber and differential flux of sodium fluorescein out of membrane-capped devices as a function of time over four successive on/off cycles of the external magnetic field; (c) schema of the proposed mechanism of membrane function.
