Abstract
A process is reported to obtain a nanoparticle sol from co-precipitated iron oxide particles without using any surfactant. The sol - a true ferrofluid - is not only stable over a wide range of pH but also in physiological solutions. This is a decisive step towards biomedical applications where nanoparticle agglomeration could so far only be prevented by using unwanted surfactants.
摘要
据报道，有一种方法可以从共沉淀的氧化铁颗粒中获得纳米颗粒溶胶，而无需使用任何表面活性剂。这种溶胶——一种真正的铁磁流体——不仅在很宽的pH范围内稳定，而且在生理溶液中也稳定。这是迈向生物医学应用的决定性一步，在生物医学应用中，到目前为止，纳米颗粒团聚只能通过使用不需要的表面活性剂来防止。
