The size distribution functions for colloidal particles in water systems were found. Information about clasterization rate of magnetic nanoparticles was obtained from comparison of the given result with data of electron microscopy. Combinations of surfactants which are lead to the least particles aggregation in the systems were discovered. Using of mono-carboxylic acids at the synthesis process leads to dispersion in water single magnetite nanoparticles with typical size distribution function of particles. Layric acid (twelve CH-group) is the best stabilizing agent among studied acids. The volume fraction of clusters in this case is just about 5 volume % . Structure parameters and interaction in aqueous micelles solution of dodecylbenzenesulfonic acid which is used for ferrofluids synthesis were studied. Concentration of micelles which are in the bulk of water-based magnetic fluids with double layer stabilization was obtained. The given work is shown perspective of mono-carboxylic usage for the synthesis of highly stable water-based magnetic fluids. The main aspect of this investigation is also biocompatibility of the mono-carboxylic acids which is opening possibility of use of the studied ferrofluids for biomedical applications.
