Figure 5: (a) Release rate of Rh(B) from MTNs and PNIPAM(0) when an AMF is applied continuously for 30 minutes. (b) Effect of iron oxide nanobeads (NBs) concentration on the release rate of Rh(B) after applying magnetic stimuli for 7 minutes. (c) Pulsatile release of Rh(B) from MTNs and PNIPAM(0) by consecutively applying an alternating magnetic field (AMF) for 6 minutes separated by 5-minute intervals without magnetic field.
