摘要：

A novel polymer gel characterized by temperature and magnetic field sensitivity has been prepared. By incorporation of magnetite nanoparticles into poly(N-isopropylacrylamide) hydrogels, we are able to target and separate the gel beads by a magnetic field; It was established that the presence of magnetic material does not modify the temperature sensitivity of these gels.
