在Fe（NO3）3和聚乙二醇的存在下，Ni（NO3）2和Co（NO3）2的声化学活化和所形成的金属氢氧化物的连续热处理的组合提供了一种廉价且有效的制备铁酸镍和铁酸钴磁性纳米颗粒的方法，其可以成功地应用于从人血清中选择性捕获荧光衍生的N-聚糖。XRD测量表明，除了铁素体相，镍和钴的氧化物也形成在热处理过程中。简单金属氧化物的量可以通过热处理的温度很好地控制，因为增加温度产生更高的尖晶石含量。对于镍和钴，发现最佳热处理温度为673 K，其中样品含有84.1%的镍铁氧体，并且在钴的情况下，可以制备几乎纯的（99.6%）钴铁氧体。FT-IR和zeta电位测量表明表面OH基团的存在，有助于颗粒在水中的分散，此外还可以促进极性化合物的吸附。磁性纳米粉末的实用性在荧光衍生的N-聚糖（来自人血清）的纯化中得到证明。钴铁氧体被认为是最有效的。由于制备简单和磁性分离的简单性，纯钴铁氧体，磁性纳米粒子可以是高效的工具，选择性富集血清N-聚糖的HPLC测量。
The combination of the sonochemical activation of Ni(NO3)2 and Co(NO3)2 in the presence of Fe(NO3)3 and polyethylene glycol and consecutive heat treatment of the formed metal hydroxides offers a cheap and efficient method for the preparation of nickel ferrite and cobalt ferrite magnetic nanoparticles, which can be successfully applied in the selective capture of fluorescently derivatized N-glycans from human serum. XRD measurement revealed that, besides the ferrite phase, nickel and cobalt oxides also form during heat treatment. The amount of simple metal oxides can be well controlled by the temperature of the heat treatment, since increasing temperature yielded higher spinel content. For both nickel and cobalt, the best heat treatment temperature was found to be 673 K, where the samples contained 84.1% nickel ferrite, and in the case of cobalt, almost pure (99.6%) cobalt ferrite could be prepared. FT-IR and zeta potential measurements indicated the presence of surface OH groups, which aided in the dispersion of the particles in water and, in addition, can promote the adsorption of polar compounds. The practical applicability of the magnetic nanopowders was demonstrated in the purification of fluorescently derivatized N-glycans (from human serum). Cobalt ferrite was found to be the most effective. Owing to the easy preparation and the simplicity of the magnetic separation the pure cobalt ferrite, magnetic nanoparticles could be efficient tools for the selective enrichment of serum N-glycans in HPLC measurements.
