Magnetic iron oxide nanoparticles grafted with poly(itaconic acid)-block-poly(N-isopropylacrylamide)

- Stimuli-responsive polymers including PIA and PNIPAM were grafted on MNPs via SI-ATRP.
- The coated MNPs were well-dispersed and stable in water and propanol.
- The thermo-responsive polymers can be used in smart drug and biomaterial delivery devices.
