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

(a) TEM images along with photographs of the different fatty acid-stabilized M³NPs (i.e., stearic acid-C₁₈, palmitic acid-C₁₆, lauric acid-C₁₂, capric acid-C₁₀, and hexanoic acid-C₆) at the same magnification (scale bar = 50 nm). (b) TEM images of stearic acid-stabilized Fe₃O₄ M³NPs with or without the addition of HA (insets are images with higher magnifications). The images clearly show the effect of HA on the size, uniformity, and dispersity of the synthesized particles.
