Ultra-Small Fatty Acid-Stabilized Magnetite Nanocolloids Synthesized by In Situ Hydrolytic Precipitation

DLS measurements of the different sized OA-stabilized M3NPs in hexane dispersions. The data clearly shows that as the (OA) molar ratios increase, the particle size decreases. However, once OA10x (i.e., 15 mmol OA) was reached, the size increases to ~20 nm, due to the worm-like streaks of aggregates formed.
