[求助] 油溶性纳米粒子改性问题

本人合成了油酸包裹的油溶性的氧化铁纳米粒子,试图在其表面引入羧基,参考以下文献的方法(In a typical experiment, Fe3O4 nanocrystals (10 mg) with
desired sizes were dissolved in 1 mL of toluene. 2,3-Dimercaptosuccinic
acid molecules (5 mg) were dissolved in 1 mL of dimethyl sulfoxide
(DMSO), and the solution is added into the nanocrystal solution. The
resulting solution was vortexed for 24 h, and black precipitates were
observed, which were isolated through centrifugation and dissolved in
water.)没有观察到相应的沉淀,明显改性不成功啊,有没有做过的虫子给指导下,谢谢! 还有没有其它比较简便靠谱的方法啊?
