Gold nanoparticles 20nm


BBI's unique recipe gold nanoparticle has been used for over 25 years due to its superior quality and performance, and features in over 400 million tests in the global market place per year.

We offer a 20nm gold which is ideal for a number of applications including Lateral flow assays, TEM, SEM, Environmental detection and purification, data storage, drug delivery, biomarkers, SERS, photo-thermolysis, catalysis, chemical sensors and DNA detection.

Gold nanoparticles are a suspension consisting of sub-micron gold nanoparticles suspended within a solvent, most often water. They have unique optical, electronic, and thermal properties and are used in a wide range of applications including diagnostics (lateral flow assays), microscopy and electronics.

At BBI we understand our customers have different requirements, so offer a range of particle sizes from 5nm to 250nm to cater to those needs, whatever the application. BBI’s unique manufacturing technique allows for the production of large batches of gold to a high level of reproducibility of size, dispersion and shape. 

The BBI difference

Used in over 400 million assays every year, our gold manufacturing technique guarantees:

• Consistency – with <5% uneven shapes and a CV of <8%, the uniform shape and size of BBI gold ensures even antibody binding, giving reliable results in your assay

• High stability – 1 year shelf life ensures a settled test manufacturing regime saving you time and wastage

• Scalability – our batch sizes go up to 350L to ensure you have continuous supply

• Quality – BBI gold must pass strict quality procedures before its released to our customers, guaranteeing impressive performance characteristics at scale
