Fe,3,O,4, magnetic nanoparticles were modified with poly (N−isopropylacrylamide) under UV irradiation. It has been found that the diameter with narrow distribution of the modified Fe,3,O,4, nanoparticles measured by PCS in aqueous solution can be controlled easily by changing concentration of monomer NIPAM and cross−linker MBA, temperature and time. It has been also shown that the modified Fe,3,O,4, nanoparticles are featured by lower critical solution temperature (LCST) while the temperature varies from 25℃ to 39℃. This may suggest promising application of the nanopartucles in medicine.
