Very interesting work, please speak about the stability of your ferrofluids.

why do you use water based ferrofluids, maybe oils could be better. have you tryed those ones?

To avoid the aggregation of the NP's is neccesary a steric repulsion. El SDS is a anionic surfactant, the sulfate anion is close to water, while that the tail (carbon docecyl) binds wakely to the surface to the particle. In the hydrodinamic size distribution its observed that covered particle has smaller size, because the SDS avoid the aglomeration for NP's.
We have not tried using oils, the idea from water as base is a greenest recovery.
