Setting the Gold Standard for Nanoparticles
Every year our colloidal gold nanoparticles are used in over 500 million assays globally and are renowned for offering exceptional assay consistency levels. Our proprietary manufacturing technique allows for the production of large volume batches of gold to a high level of reproducibility of size, dispersion and shape, and we maintain this through tight quality control release specifications. This ensures a firm foundation for conjugation and peace of mind that your assay will provide reliable results.
BBI Solutions have been manufacturing high-quality gold nanoparticles for over 30 years, making us the trusted partner for thousands of researchers, lateral flow assay developers and manufacturers worldwide.
Delivering exceptional quality gold colloid, time after time
At BBI we understand our customers have different requirements, so we offer a range of gold nanoparticle sizes from 2nm to 250nm to cater to those needs, whatever the application.
Our proprietary manufacturing technique delivers:
Uniformity
With ≤5% odd 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
BBI particles are proven stable for at least twelve months and are supplied with a minimum of three month’s expiry. Stable particles ensure a settled testing regime, saving you time and wastage.
Scalability
Our batch sizes go up to 340l (40nm) to ensure you have a continuous supply.
Quality
BBI gold must pass strict quality procedures before it's released to our customers, guaranteeing impressive performance characteristics at scale.
Gold nanoparticle applications
BBI Solutions’ gold nanoparticles are renowned for their use in lateral flow tests; however, the use of nanoparticles ranges from health and material technology to the environment and energy sectors as detailed in the table below.

Advantages of outsourcing
There are many hidden costs in producing gold nanoparticles and conjugates in-house. By outsourcing manufacture to BBI, you can benefit from:
More R&D time
Valuable R&D time is freed up to concentrate on the development of your assay systems
More tests per litre of gold
Using BBI gold colloid results in more tests per volume of conjugate, because consistent gold means less waste
A faster route to market
By using BBI gold you can avoid delays caused by using a poor, inconsistent gold label, and commercialise your assay faster
