Nanopartz™ Custom Charged 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 charge requirements: negative, neutral, and positive. Not only is every batch completely purified, it is characterized including size, charge, 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.
Nanopartz nanoparticles are available with distinct surface charges to optimize performance in biomedical research, drug delivery, diagnostics, catalysis, and other advanced fields.
Positively Charged Gold Nanoparticles
- Surface Functionalization: These nanoparticles are functionalized with cationic agents, offering superior performance in binding negatively charged biomolecules, such as DNA or proteins.
- Applications: Perfect for DNA delivery, cell targeting, and gene therapy research.
Negatively Charged Gold Nanoparticles
- Surface Functionalization: Functionalized with anionic groups, our negatively charged gold nanoparticles are ideal for use in applications where you need a strong repulsion from other anionic species.
- Applications: Effective in drug delivery systems, bioconjugation, and biosensing applications.
Neutral Gold Nanoparticles
- Surface Functionalization: Our neutral nanoparticles are available with surfaces designed to minimize non-specific interactions, ensuring stability in various environments.
- Applications: Excellent for catalysis, drug delivery, and therapeutic treatments where neutral interactions are essential.
Customizable Surface Functionalization
Our gold nanoparticles are fully customizable, enabling you to select the exact surface charge, ligand, and size to match your experimental or commercial needs. Whether you require nanoparticles for diagnostics, drug delivery, or material science research, NanoPartz is equipped to provide the highest quality solutions. Let us know your requirements and we will quote!

Functionalized gold nanoparticle with Nanopartz™ covalently bonded non reactive polymer
Composition
These gold nanoparticles are shipped concentrated in water.
Toxicity
These particles are non cyctoxic.
Quantity
This product is available in OD=50 for the nanorods and spheres, and 0.25mg for the microgold and nanowires. For orders larger than 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
Polymer coatings are non reactive and covalent. Purification is a multistep dialysis resulting in less than 0.01% w-w reactants. Zeta potential ranges from -30mV to +30mV for all particles.
Buffer
18MEG DI water.
Shelf Life/Storage Temperature
This product is guaranteed for three months and should be stored in a non freezing refrigerator.
Sterilization
Customers have a choice of sterilization and endotoxin free forms.
Certifications
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
What is the exact charge on the particles?
That will be determined via DLS Zeta measurements and included on the COA. In general, the charges are -30, 0, and +30mV.
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.
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.
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?
Yes
Can I suspend in silicon oil?
No
What is the shelf life if I never open the package and keep refrigerated?
One year
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 OD?
Optical Density (OD) is measured by UV-VIS. An Optical Density OD=1 corresponds to a transmission of 10% through a 1cm cuvette. Optical Density is a nice unit to use since Optical Densities correlate linearly to concentration. So an Optical Density of 1.2 is equal to 1.2 times the concentration of a gold nanoparticle solution that has an Optical Density of 1. We use OD and concentration interchangingly as it is easier to refer to a solution of OD=1 rather than 2.35e12 nanoparticles. For all spheres up to 200nm, OD=1 does refer to 0.05mg/mL.
What is PDI?
PDI refers to polydispersity index and is equal to the standard deviation of the particle sizes divided by the average size.
"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."
