"I have been using the Nanopartz Organic Spherical Gold Nanoparticles in my research and they have worked extremely well due to the moderate hydrophilicity and high concentration. I highly recommend this product."
These particles utilize a Nanopartz™ formulated coating that shields the particle from the effects of abrasive solvents, and yet, still provide the optical properties inherent to the particles.

Bare Gold Nanorods with organic coating agent
These gold nanorods are shipped in a small amount of a short chained alkane alcohol - the product has a zeta charge is +/-5 mV depending on the construct. If you are using this product for research and need to know the exact composition, please go to our analytical gold nanoparticles where you can choose the exact polymer you'd like to use.
This product is available in 2.5mg and 5mg for the spheres, OD 50 and 250 for the nanorods and Plasmonic Fluorophores™ and 0.25mg for the microgold and nanowires. For larger orders, please contact sales for quantity pricing.
Unfortunately there are no kits available for this product at this time.
All are in stock and ship fedex.
This product is not conjugatable.
Add solvent dropwise to nanomaterial. Disperse using sonication or vortexing. Organic nanoparticles will stay suspended from days to weeks depending on solvent. Suspension may be monitored through UV-VIS spectra.
Shelf Life/Storage Temperature

The cytotoxicity of this product is unknown.
This product is biological free.
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
For detailed specifications, please refer to the product family pages for those products. The coating compounds adds an unmeasurable thickness to the particles as the PDI of the particles is greater than the thickness of the polymer.
How much thickness does your proprietary capping agent add?
It is less than the variablility of the size of the nanoparticles themselves, so it is unmeasurable.
How do I determine the concentration of the product?
Simply divide the number of nanoparticles (nps) found on the included COA by the amount of solvent you add.
Why do you sell your rods as OD-mLs and what does this mean?
This is because unlike spherical gold nanoparticles, the conversion from OD to mg is not linear with nanorod diameter. Consequently, for the same OD, the weight of the nanorods increases with diameter. 50 OD-mLs means that if you resuspend the material in 1mL of solvent, you will have an absorption of OD50 through a 1mL optical path.
Can I resuspend in water?
Can I suspend in silicon oil?
Will the SPR wavelength shift with different solvents?
The SPR is a function of the index of refraction of the host solvent in which the nanoparticles are suspended. Nanorods are the most sensitive and are therefore a great tool for measuring the index of refraction of the host.
What is the shelf life if I never open the package?
Should I store in the refrigerator?
It is not necessary.
Is this product good for spin coating?
Yes, if brought up in ethanol, they make for a very good material.
