Water-Soluable Ferromagnetic Compounds
« on: July 05, 2010, 02:02:20 PM »
I've hit a major snag in a prpject im working on.  I have been trying to find a cheap water-soluable ferromagnetic compound and all I have been able to find is a group of coumpounds called siderophores which are extremely expensive.  I am open to any ideas. Many thanks

I think it already exists. Here is an example to make an aqueous ferrofluid http://www.mrsec.wisc.edu/Edetc/nanolab/ffexp/. I haven't tried it, so I don't know if it actually works.

Here are two videos of a ferrofluid in the presence of a magnet http://www.youtube.com/watch?v=PvtUt02zVAs and http://www.youtube.com/watch?v=ULSG3pkjoT4. Looks cool  :D

I apologize for not including this earlier but the molecule would have to be larger with a mw around 200-400g. Thats what the major trouble has been and is why I've only been able to find siderophores.
