“…Magnetite nanoparticles have been used in a wide range of applications including hyperthermia,10 purification,11 immobilization,12, 13 catalysis,14–16 magnetic resonance imaging,17–20 memristors,21 electrochemistry,22 etc. When magnetite nanoparticles are coated with polymers, the resulting hybrid magnetic nanoparticles have the advantages of good dispersibility and high stability, and the functional groups at the surface can be used for further functionalization 23–26. Magnetite–polymer hybrid nanoparticles have demonstrated promise towards the development of new targeted agents for cancer diagnosis and therapy because they can be manipulated using an external magnetic field gradient to control targeted delivery and drug delivery 27–34…”

Multifunctional hybrid nanoparticles, Fe 3 O 4 @poly[(2-dimethylamino)ethyl methacrylate]-block-poly(2-hydroxyethyl methacrylate)-graft-carbazole, with pH-responsivity, superparamagnetism and fluorescence for targeted drug delivery and release have been synthesized. The nanoparticles have a core-shell structure as determined from transmission electron microscopy, pH-responsivity as determined from hydrodynamic radius analysis, superparamagnetism as determined from vibrating sample magnetometry and fluorescence as determined from fluorescence spectroscopy and fluorescence microscopy. The release behavior of model drug progesterone indicates that the release rate can be effectively controlled by altering the pH of the environment. The multifunctional nanoparticles could be applied extensively in targeted drug delivery and release, and with fluorescence they can serve as efficient tracers to record magnetic targeting routes. Scheme 2. Schematic of effect of change of pH.

This paper describes the preparation of the metallic affinity column by atom transfer radical polymerization of glycidyl methacrylate (GMA) on Wang resin surface. The metallic ions (Zr 4þ , Fe 3þ , and Pd 2þ ) were introduced after phosphonation of the epoxy group of the grafted poly(GMA) on Wang resin surface. The successful results on metallic ion-immobilized polymeric microsphere stationary phase were confirmed via Fourier transform infrared, scanning electron microscopy, X-ray photoelectron spectra (XPS), and inductively coupled plasma-atomic emission spectrometer. The resolution degree of the phosphonated casein and dephosphonated casein for Zr 4þ , Fe 3þ , and Pd 2þ affinity column was examined. The result shows that the resolution time (min) of the phosphonated casein was higher than that of the dephosphated casein on the Zr 4þ affinity column by liquid chromatography. However, the phosphonated casein and dephosphonated casein were not separated on the Fe 3þ affinity column and Pd 2þ affinity column by liquid chromatography.
