These particles utilize Nanopartz expertise as world leaders in gold conjugation and polymer coatings. Utilizing Nanopartz capabilities, customers now have the ability to create specific charged particles. custom charges on gold nanoparticles. Customers detail the charge desired, and Nanopartz provide the resultant product completely characterized using NIST traceable TEM, UV VIS, DLS, HPLC, and ICP instrumentation. Most importantly, the customer will know the exact zeta potential of the nanoparticles and will be given options for sterilization and for endotoxin free products.


  1. Stable
  2. Well Characterized
  3. Customer can select gold nanoparticle type, size and/or SPR and charge


  1. Customer can focus on research and not on Nanopartz expertise
  2. Quick turnaround

22, 32, 52, 72-NS MSDS


What is the exact charge on the particles?

That will be determined via DLS Zeta measurements and included on the COA. In general, the charges are -30, 0, and +30mV.

Can I choose any buffer?

That depends on the requested conjugation, but in general, yes. We will advise if we don't think that a particular buffer is optimal for a particular product.

Can you help me put together procedures to use the product?


Can you perform these conjugations and still keep the nanorod SPR where I specify?


Can you work with very short covalent ligands, like 4 carbon lengths and have the particles stable?
