Magnetic Core-shell nanoparticles with molecularly imprinted polymers for selective adsorption and separation of adenine.

Magnetic Core-shell nanoparticles coated with an adenine-imprinted polymer layer were successfully synthesized. The morphology of the nanoparticles was characterized by transmission electron microscopy (TEM). The nanoparticles have a definite core-shell structure and an imprinted polymer layer. The adsorption, recognition and reusability of the molecularly imprinted nanoparticles were analyzed by static/dynamic adsorption, competitive adsorption and reproducibility experiment. The magnetic molecularly imprinted nanoparticles exhibit fast adsorption, high adsorption capacity, strong specificity and satisfactory recovery. [ABSTRACT FROM AUTHOR]
