Key Features:
-
Hydrophobic Gold Nanoparticles: Ideal for nonpolar solvents, enabling their use in organic synthesis, coatings, and specific drug formulations.
-
Hydrophilic Gold Nanoparticles: Fully soluble in water, perfect for biomedical applications like imaging, diagnostics, and aqueous-phase reactions.
-
Amphiphilic Gold Nanoparticles: Designed for dual-environment compatibility, these nanoparticles excel in emulsions, self-assembling systems, and targeted drug delivery.
Applications:
Biomedical Research and Diagnostics:
-
Hydrophilic Gold Nanoparticles are utilized in bioimaging techniques like fluorescence microscopy and X-ray imaging due to their excellent solubility and stability in biological systems. These nanoparticles enhance contrast and precision.
-
Amphiphilic Gold Nanoparticles can cross biological membranes, making them ideal for drug delivery and biodistribution studies. They improve the solubility of hydrophobic drugs while ensuring targeted delivery.
Material Science and Industry:
-
Hydrophobic Gold Nanoparticles are essential in coatings, nanocomposites, and catalysis within organic solvents, ensuring robust performance where water-based particles are ineffective.
-
Amphiphilic Gold Nanoparticles play a crucial role in creating emulsions and stabilizing complex systems, from cosmetics to advanced lubricants.
Drug Delivery Systems:
-
Amphiphilic nanoparticles enable encapsulation and delivery of hydrophobic drugs in water-based systems, offering controlled release and enhanced bioavailability.
Customization Options:
We understand that every application has unique requirements. Our gold nanoparticles can be customized in terms of:
-
Size (ranging from 2 nm to 10000 nm).
-
Surface functionalization (fluorophores).
-
Solubility properties (hydrophobic, hydrophilic, or amphiphilic coatings).
Why Choose Our Gold Nanoparticles?
-
High Purity: Precisely engineered with minimal impurities for consistent results.
-
Versatility: Suitable for diverse applications across multiple industries.
-
Custom Solutions: Tailored to meet your exact specifications.

Functionalized gold nanoparticle with Nanopartz™ covalently bonded hydrophobic, hydrophilic or amphiphilic polymer
Composition
These gold nanoparticles are shipped concentrated in water.
Toxicity
Toxicity is dependent on solvent.
Quantity
This product is available in 50 OD-mLs 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
Within 1-2 days.
Conjugations
Polymer coatings are non reactive and covalent.
Buffer
Dependent on Solvent
Shelf Life/Storage Temperature
This product is guaranteed for three months and should be stored in a non freezing refrigerator.
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 difference between hydrophobic, hydrophilic, and amphiphilic gold nanoparticles?
Hydrophobic gold nanoparticles are non-water-soluble and ideal for organic systems, hydrophilic nanoparticles dissolve in water and are used in biological applications, and amphiphilic nanoparticles combine both properties, making them versatile for mixed environments.
Can I customize the surface properties of the nanoparticles?
Yes, we offer fluorophore labeling.
What sizes are available?
Our nanoparticles range from 2 nm to 10000 nm, with specific sizes available upon request.
Are these nanoparticles biocompatible?
Yes, our hydrophilic and amphiphilic nanoparticles are biocompatible, making them ideal for in vivo applications like imaging and drug delivery.
Do you provide bulk orders?
Yes, we accommodate both small-scale and bulk orders to suit academic, industrial, and commercial needs.
Can I choose any solvent?
We will choose water for hydrophilic, and offer you your choice for hydrophobic and amphiphilic.
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.
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."
