Description générale
Iron oxide(II,III), magnetic nanoparticles solution (Fe3O4) is an organic solvent dispersed nanoparticle solution, which can be synthesized by the thermal decomposition of iron acetylacetonate in 2-pyrrolidone. It is majorly used in biomedical applications due to its magnetic properties, particle size, and surface properties.[1][2]
It contains <1.0% oleic acid stabilizing ligands.
It contains <1.0% oleic acid stabilizing ligands.

What is the coating thickness of oleic acid on product number 700312, 700320, and 700304, Iron oxide(II,III), magnetic nanoparticles solution?
1 answer-
The suppliers of the magnetic iron oxide nanoparticles in toluene have indicated that the particles are essentially coated with a monolayer of oleic acid. Since the oleic acid is a long chain hydrocarbon there can exist some folding and irregular structure on the surface. The suppliers estimate that one should add 1-2 nm to the particle size due to the presence of the oleic acid coating. From this, 1.5 nm is the closest approximation of coating thickness as provided by our suppliers.

How should a sample of the Iron oxide(II,III), magnetic nanoparticles solution in toluene be prepared for analysis by transmission electron microscopy (TEM)?
1 answer-
The particle size is determined by TEM.If the solution as provided is not diluted, a superlattice of multilayer nanocrystals will form on the grid, appearing to be an aggregate. The solution can be diluted with the same solvent that it was shipped in (toluene). A solution diluted to 0.1-0.5 mg/mL should be concentrated enough to get a nice picture. One drop per grid should be sufficient. (Since the solution is provided at a concentration of 5 mg/mL, this would be a 10- to 50-fold dilution.)After applying the sample to the grid, a drying time of a minimum of 10-15 minutes is recommended.After performing several successful dilutions and getting good results, the analyst will get a feel for the correct dilution just by judging the color and darkness of the diluted sample. If you see lone isolated dots in the TEM, then your sample is too dilute. If you cannot distinguish separate particles, it is too concentrated. Good record keeping will help to zero in on the best dilution factor for the type of picture that you want.
