Nanopartz™ Custom Conjugated Gold Nanoparticles for Analytical Applications

Nanopartz™ Custom Conjugated Gold Nanoparticles includes the full line of monodisperse spherical, rod, microgold, and nanowire product familes for conjugation to molecular surface modifiers (MSMs). We have extensive experience and inventory in conjugating the most popular covalent alkyl, functional, protected, ring and other self assembly materials on gold nanoparticles. 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.

Composition

These bare gold nanoparticles are shipped highly concentrated.

Quantity

This product is available in ~2.5mg and ~12.5mg (depending on size) for the nanorods and spheres, and 0.25mg for the microgold and nanowires. For orders larger than 12.5mg, or for orders amounting over 100mg per annum, please contact sales for quantity pricing.

Delivery

All gold nanoparticles are in stock. Conjugation depends on materials needed. If in stock, the product is ready in 24 hours and will ship fedex. Overnight service is not required for this product and it will ship on weekends.

Conjugations

Molecular surface materials.

Buffer

DI water, ethanol, toluene, or by customer specification.

Shelf Life/Storage Temperature

This product is guaranteed for two months and should be stored in a non freezing refrigerator.

Certifications

This product is manufactured using our audited ISO 9000/2001 quality control system. Every order comes with a Certification of Analysis that includes the following information. We use NIST traceable:

UV-VIS (Agilent 8453) for extinction and concentration measurements

NIR (Cary 500) for NIR extinction and concentration measurements

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 analytical 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.

 

There are no other products offered by any other technology.

 

  • Stable
  • Well Characterized
  • Customer can select buffer (limited)
  • Customer can select gold nanoparticle type, size and/or SPR
  • Loading of all ligands is optimize
  • Customer can focus on research and not on Nanopartz expertise
  • Quick turnaround

 

B11-60-DDT

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 were previously making our own gold nanoparticles using the commonly used technique of citrate reduction of Au(III). The colloids generated are broadly polydisperse, and we were concerned that our application of these particles in immuno-gold labeling of cells for optical coherence microscopy (OCM) would be utilizing only the large diameter tail of the distribution. We purchased the sampler package of NanoPartz gold spheres (30 nm, 50 nm, 70 nm, 90 nm) and examined each size carefully with dynamic light scattering, OCM, and spectrophotometry. Our measurements indicated diameters a couple nanometers larger than specifications (a result of measurements on the fully hydrated state?), and remarkable monodispersity - within specs. It is clear to us now that our early immuno-gold results were dominated by the largest diameter spheres of our early colloids. We are delighted by the NanoPartz monodisperse preparations and recommend them strongly!"

"The scientists at Nanopartz have developed a line of colloidal gold nanorods with extremely high monodispersity in size, shape, and mass. The surfactant layer is highly stable and readily displaced for biofunctionalization. In every test, in vitro and in vivo, these materials have exceeded our expectations."
