Utilizing Nanopartz™ capabilities, customers now have the ability to have custom gold nanoparticles and conjugation made for research purposes. Customers detail the ligands wanted, 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 loading of the nanoparticles and will be given options for sterilization and for endotoxin free products.

Custom Conjugated Gold Nanoparticles

FAQz

Will you provide me the loading for the reactive groups for my journal paper?

Yes

Will you provide me a Certificate of Analysis containing all the necessary information for my journal paper?

Yes.

Will you disclose details on how you manufacture the product?

Unfortunately no.

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?

Absolutely.

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

Yes.

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

Yes!

Testimonials

"We have looked at many different gold nanoparticles samples from Nanopartz including spheres, rods, and microrods using single particle spectroscopy techniques and are extremely happy with the quality of the samples and the service provided by Nanopartz."
