Ultra Uniform Gold Nanoparticles
Plasmonic gold nanoparticles are widely used in diagnostics, biomedical therapies, and optical research. For applications requiring the highest uniformity in size and shape, our Ultra Uniform Gold Nanospheres are available. These particles have a nearly perfect spherical shape, smooth surfaces, and impressively narrow size distributions (CV < 5-6%).
Our Ultra Uniform Gold Nanospheres are provided
- With TEM, UV-Vis, and DLS data for every batch
- As standard sizes from 10-100 nm, and custom sizes up to 200 nm in diameter
- At a concentration of 0.05 mg/mL (gold content) in a 2 mM sodium citrate solution
- Capped with a carboxyl-terminated ligand
Optical and Scattering Properties
Due to their high uniformity in size and shape, these Au nanospheres scatter a single color of light under dark field microscope imaging (shown below). The high purity of their light scattering signatures makes these nanospheres perfect scattering labels for imaging and building blocks for plasmonic nanostructures and devices. Shown below are dark field images of the scattered light from 50 nm (left) and 100 nm (right) Ultra Uniform Gold Nanospheres.
Need something a little different? Like many of our nanomaterials, we can customize the size and surface functionality of the Ultra Uniform Gold Nanospheres for your application.
The Ultra Uniform particles can be coated with polystyrene and dispersed into organic solvents, conjugated to antibodies for biological recognition, or modified in many other ways.
