20 nm Gold Nanoparticles
• Bare surface and stability for sequential conjugations
• Laser-made for high purity
• Produce conjugates for imaging and targeting
Overview
The high purity, stability, and bare surface of i-colloid 20 nm gold nanoparticles allows production of conjugates sequentially functionalized with multiple ligands at controlled surface density for imaging, targeting, and other tunable properties. IMRA’s laser-ablation process allows Au20 to be a cost-effective solution for assay development.
