英文摘要in this study, we report a novel method to synthesize core-shell structured fe3o4 nanoparticles (nps) covalently functionalized with iminodiacetic acid (ida) via click chemistry between the azide and alkyne groups and charged with cu2+. firstly, the fe3o4@sio2 nps were obtained using tetraethoxysilane (teos) to form a silica shell on the surface of the fe3o4 core. the azide group-modified fe3o4@sio2 nps were obtained by a sol-gel process using 3-azidopropyltriethoxysilane (azptes) as the silane agent. fe3o4@sio2-n-3 was directly reacted with n-propargyl iminodiacetic via click chemistry, in the presence of a cu(i) catalyst, to acquire the ida-modified fe3o4 nps. finally, through the addition of cu2+, the fe3o4@sio2 ida-cu np product was obtained. the morphology, structure and composition of the nps were characterized by transmission electron microscopy (tem), x-ray powder diffraction (xrd), fourier transform infrared (ftir) spectroscopy and x-ray photoelectron spectroscopy (xps). the resulting nps showed a strong magnetic response to an externally applied magnetic field, a high adsorption capacity and excellent specificity towards hemoglobin (hb). in addition, the fe3o4@sio2-ida-cu nps can be used for the selective removal of abundant hb protein in bovine and human blood samples.
