OBJECTIVE In medicine, there is limited knowledge on the toxicity of nanoparticles particularly concerning the effect of nanoparticles in milk. Here, the authors reported the effect of gold nanoparticles in milk specimens.

METHOD This study was performed as an experimental study. A mixture of gold nanoparticle solution and milk sample was prepared and analyzed.

RESULTS According to this study, after mixing the milk sample with gold nanoparticle solution, fine aggregated particles were observed.

CONCLUSIONS It was demonstrated that gold nanoparticles can cause bonding of the protein in the milk. This could lead to further toxicity in infants ingesting contaminated milk.

Key words: Gold nanoparticles, Milk, Toxicity.
