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

Figure 3

FTIR spectra for OA-stabilized Fe₃O₄ M³NPs. The spectra clearly show the intensity of the characteristic vibrational modes ascribed to OA molecules (inset: TGA analysis of OA-stabilized M³NPs exhibited a weight loss ~24%, implying the successful coating of the as-synthesized M³NPs with OA).
