Overview of 40 nm Reactant Free Gold Nanoparticles

Inquiry

Description

The reactant free gold nanoparticles of 40 nm we offer are a type of nanoparticle suspension containing gold nanoparticles. Its main benefits are high purity and stability. Since no chemical reactants are used in the synthesis process, the resulting nanoparticles are free from any residual chemicals or impurities that could potentially affect their properties or applications. This high level of purity also contributes to the stability of the suspension, as there are fewer factors that could lead to aggregation or degradation of the nanoparticles over time.

Properties

Our 40 nm reactant free gold nanoparticle preparations have a tight size distribution (CV <12%), excellent protein adsorption abilities and more than 95% spherical particles. And with low batch-to-batch variability (+/- 2nm), you can trust that you'll always receive a product within the specified size range. In addition, each of our batches undergoes rigorous quality control using dynamic light scattering to ensure size and monodispersity, and lot specifications are provided with every product shipment. 

Intended Use

Our highly purified 40 nm reactant free gold nanoparticles are ideal for sensitive applications. For example, they are well suited for conjugate development by passive adsorption of proteins and other ligands to the gold nanoparticle surface. The resulting conjugate can be used in blotting, electron microscopy and immunohistochemistry applications.

Storage

• Store the product at 4-25 °C away from direct sunlight. Cooler temperatures extend the shelf life of the product.
• Do not freeze. Freezing causes irreversible aggregation of the gold nanoparticles.
• The product is stable for at least six months when stored as specified.
