Nanopartz™ Custom Conjugated Gold Nanoparticles

Nanopartz™ Custom Conjugated Gold Nanoparticles includes the full line of monodisperse spherical, rod, microgold, and nanowire product familes for conjugation to customer specified ligands. We have extensive experience and inventory in conjugating the most popular covalent and charge based conjugations including Polyethylene Glycol (PEG), polystyrene, and more with the customer selected buffer. Upon conjugation, not only is every batch is completely purified, it is characterized including size, monodispersity, aggregation, residual chemicals, and concentration. A Certificate of Analysis (COA) is provided for every order exhibiting TEM and UV-VIS images and data, as well as DLS data. Customers have a choice of radiation sterilization and endotoxin postprocessing. This product is submitted for quotation through email. We normally respond within 1 hour. Products are normally ready for shipping within 24 hours of ordering. Prices start as low as $350.

DLS (Malvern Nano ZS) for zeta potential measurement

ICP-MS (Varian 820-MS) for gold mass measurements

TEM (Phillips CM-100 100KV) for sizing

These particles utilize Nanopartz™ expertise as world leaders in gold conjugation. 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

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!

"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."
