Illustration of the mechanism of drug release from a multi-stimuli responsive doxorubicin loaded hydrogel. (a) Physiological temperature (37 °C) causes the hydrogel to collapse and release doxorubicin; with time it regains its original state and (b) shows the application of external magnetic field causing the polymer network to vibrate and release doxorubicin via increased diffusion rate.
