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. Customers have a choice of radiation sterilization and endotoxin postprocessing.

Custom Charged Spherical Gold Nanoparticles (2.5mg in 1mL)
Custom Charged Gold Nanorodz™ (OD 50 in 1mL)
Custom Charged Microgold
Custom Charged Gold Nanowires
These particles utilize Nanopartz™ expertise as world leaders in gold conjugation and polymer coatings. Utilizing Nanopartz™ capabilities, customers now have the ability to have custom charges on gold nanoparticles. Customers detail the charge desired, 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 zeta potential of the nanoparticles and will be given options for sterilization and for endotoxin free products.
- Well Characterized
- Customer can select gold nanoparticle type, size and/or SPR and charge
- Customer can focus on research and not on Nanopartz™ expertise
- Quick turnaround

Choose By Charge Gold Nanoparticles
These gold nanoparticles are shipped in water at volumes from 25mL and greater.
This product is available in 2.5mg and 5mg 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.
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.
Polymer coating with methyl, carboxyl, amine and bromine capped gold nanoparticles. Zeta potential ranges from -30mV to +30mV for all particles.
Shelf Life/Storage Temperature
This product is guaranteed for two months and should be stored in a non freezing refrigerator.
Customers have a choice of sterilization and endotoxin free forms.
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.
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.
Can you help me put together procedures to use the product?
Can you perform these conjugations and still keep the nanorod SPR where I specify?
Can you work with very short covalent ligands, like 4 carbon lengths and have the particles stable?
