Gold Nanoparticles

Nanotechnology refers to science dedicated to materials having dimensions in the order of 100nm or less.

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.

Gold in rapid diagnostic tests

The quality and performance of a conjugate is critical to achieving consistent, accurate results in lateral flow tests. Gold nanoparticles offer excellent stability and sensitivity. As the demand for increased sensitivity grows, gold has become regarded as a reliable raw material to provide an accurate visual reading.

Good gold versus bad gold

good gold nanoparticles versus bad gold nanoparticles

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. This ensures a firm foundation for conjugation and peace of mind that your rapid assay will provide reliable results.

This is not the case for all gold nanoparticles. Understand the benefits of using good gold. Take a look at our movie »

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

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 results in more tests per volume of conjugate, because consistent gold means less waste

• A faster route to market: using BBI gold you can avoid delays caused by using a poor, inconsistent gold label, and commercialise your assay faster

• Enhanced sensitivity: 25 years of experience and our proven track record in manufacturing gold nanoparticles will put you one step ahead of the competition

Goldlink kits conjugation procedure

Alternatively, our GoldLink™ kits are designed for early stage R&D, where you may need to quickly explore the viability of a range of antibodies, before the conjugate is optimised on a larger scale.

Screen your antibodies of choice in-house in a cost effective way, before using our custom conjugation service to progress your development.
