请问，怎么对Fe3O4进行氨基化/羧基化？ 各位能不能推荐一下文献（期刊，论文标题，卷期，页码）？我想学习一下。谢谢！ |

你看看这两篇papers,希望能有点用处。另外孙老师组里一直做磁性纳米材料，你可以再搜索一下他们的paper。 1) He, Y.P.; Wang, S.Q.; Li, C.R.; Miao, Y.M.; Wu, Z.Y.; Zou, B.S.; Synthesis and characterization of functionalized silica-coated Fe3O4 superparamagnetic nanocrystals for biological applications, Journal of Physics D: Applied Physics, Volume 38, Number 9, 7 May 2005 , pp. 1342-1350(9)[ 被引用次数：11] Abstract: Superparamagnetic Fe3O4 nanocrystals were prepared by a chemical coprecipitation method with a thin thickness-adjustable silica layer coated on the surface by hydrolysis of tetraethyl orthosilicate. The silica-coated Fe3O4 nanocrystals were well dispersed and consisted of a 6–7 nm diameter magnetic core and a silica shell about 2 nm thick, according to transmission electron microscopy observations. Fourier transform infrared spectra revealed that amino (–NH2) groups were successfully covalently bonded to the silica-coated Fe3O4 and then carboxyl (–COOH) groups were functionalized to the surface through the reaction of –NH2 and glutaric anhydride. ............... 2)J.
