Gold Nanoparticles in Organic Solvents - Nanopartz
Nanopartz™ Organic Gold Nanoparticles includes the full line of Monodisperse Spherical Gold Nanoparticles, Gold Nanorods, Microgold, and Gold Nanowire product familes for use in organic applications. This product offers four different options: (1) Polyvinylpyrrolidone (PVP); (2) Polystyrene; (3) our proprietary Nanopartz Organic coating; and (4) our proprietary Nanopartz Organic conductive coating. A comparison of the the four coatings are shown in the specifications tab. Gold Nanoparticles purchased with our proprietary Nanopartz Organic Polymer in a metamaterial state are guaranteed stable for resuspension in almost any solvent (please contact us for solvents not listed in the following table). Every batch is completely characterized. A Certificate of Analysis (COA) is provided for every order exhibiting TEM and UV-VIS images and data, as well as DLS data. For self assembled monolayers (e.g. alkanethiols), please go to Analytical Gold Nanoparticles. Every product is in stock (99%) and is shipped next day. This product is perfect for optical coatings, polymers, and solar cell applications.

Composition
These nanoparticles are shipped dried ready for resuspension in the solvent of choice with no measurable residual reactants.
Custom Formulation
Please contact us.
Quantity
This product is available in 0.25mL volumes and larger. This product is expected to be diluted.
Introductory Kits
Please contact us.
Delivery
Standard sizes are in stock. Special order sizes are shipped in two weeks or less. All domestic shipments are sent Fed Ex Standard Overnight delivery, international Fed Ex Priority 2 day. No shipments on Fridays except for dried particles. Saturday shipping available for extra charge.
Functionalization
This product comes with a number of different options that are further functionalizable. For the most readily functionalizable, please choose PVP.
Shelf Life/Storage Temperature
This product is guaranteed for six months and should be stored at 4 °C after opening. Care must be taken to only use sterile glassware when working with this product.
Toxicity
This product is known to be noncytotoxic (other than the solvent other than the solvent the customer adds).
Certifications
Every order comes with a Certification of Analysis that includes the following information. We use calibration 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
TN801 UV VIS to Determine Size and Concentration
Note: SDS are based on solvent. Please request an SDS for your solvent
How much thickness does your proprietary capping agent add?
Anywhere from 1-5nm.
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 solution you add.
What is a metamaterial?
This is where the concentration is so high, the product acts like mercury. It is essentially dry.
What can I resuspend the metamaterial into?
Any solvent!
Can I resuspend in water?
No
What is the shelf life if I never open the package and keep refrigerated?
Many years.
Should I store in the refrigerator?
Yes.
How do you size your gold nanoparticles? Does the size include the capping agent?
We use three methods to specify our gold nanoparticles; TEM, UV VIS, and DLS. Each has its own advantages and disadvantages, and we use a weighted system to take advantage of each methods strengths. In the end, we place the strongest weight to the TEM method, particularly since we use samples sizes greater than 50 particles for each lot.
Do you really provide a TEM for my specific lot?
Yes, and not just for 5-10 particles, rather 50-100 are standard.
What is PDI?
PDI refers to polydispersity index and is equal to the standard deviation of the particle sizes divided by the average size.
What if I need to know the polymer being used?
Choose Polystyrene.
What if I need a readily replaceable polymer so I can do further conjugations?
Choose PVP.
"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 NPO - 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. When shipped as a metamaterial form, can be resuspended in any solvent.
