Gold Nanoparticles Ultrapure Colloids

This figure shows transmission electron microscopy (TEM) images of ultrapure 3 nm and 10 nm gold nanoparticles.

Product Introduction:
Gold nanoparticles ultrapure colloids are suspensions of gold nanoparticles with high purity and good stability. The term "ultrapure" indicates that these suspensions are free from contaminants and impurities, which ensures that the gold nanoparticles perform consistently and reliably. These products have a wide range of applications in biomedical, sensing, catalytic, electronic and scientific research due to their unique properties.

You Need to Know

Synthesis: Synthesis by pulsed laser ablation in liquids (PLAL) technique to guarantee pureness. The gold film was processed in an automatized flow chamber system using ultra-pure Milli-Q Water stabilized with micromolar concentration of NaCl solution.
Storage: Store the products away from direct sunlight at 4-25 °C. Lower temperature prolongs shelf life. Do not freeze. Nanoparticles can be sensitive to high and low pH conditions and high salt concentrations. Use caution when changing environmental conditions.
