Cytodiagnostics Azide functionalized gold nanoparticles are suitable for covalent conjugation of any molecule with a terminal alkyne through click chemistry. 

These gold nanoparticles allow for rapid generation of gold conjugates and unique gold nanoparticle surface chemistries. 

Our Azide functionalized gold nanoparticles are available in 12 different sizes ranging from 5 -100nm, are more than 95% spherical and have uniform size distribution (CV <12%). 

All of our batches go through stringent quality control prior to shipment to our customers using dynamic light scattering to guarantee size and monodispersity and lot specifications are supplied with each product.


Store product away from direct sunlight at 4°C. Do NOT freeze. When stored as specified the product is stable for at least twelve months.
