maghemite

anionic maghemite nanoparticles allow labeling of a wide cell variety and their recognition in cellular, organo typical, and animal models.

阴离子磁赤铁矿纳米颗粒能够标记多种细胞，并用于细胞、器官和动物模型的识别。

maghemite is directly prepared by pyrolysis of ferrous hydroxide as precursors in the presence of co2-3 with microwave irradiation.

用硫酸亚铁为原料加NH3·H2O得到的Fe（OH）2作前驱物，在有CO32-存在下进行微波快速热解可直接得到γ-Fe2O3。

materials and methods: nanometer-sized, dextran-coated (maghemite) io particles were prepared by a precipitation method.

材料和方法：用沉淀法制备纳米尺度的葡聚糖包裹（磁赤铁矿）IO颗粒。
