A revolutionary new generation of nanoparticles, unprecedented on the world market

SON SAS is a pioneering leader in the field of nanoengineering, specialising in the design and production of HIGH-PRECISION nanoparticles.


Your teams can work according to consistent specifications and properties, facilitating experiment reproducibility and ensuring more robust and reliable results.

Highly characterised

You know exactly what you are buying. Each batch comes with a detailed certificate of analysis.

This data allows you to quickly and easily verify the quality, reliability, biocompatibility, and compliance of the nanoparticles you intend to use in your work.



The use of pure nanoparticles results in higher quality data as uncontrolled variables linked to contamination are eliminated.


Multifunctionalised nanoparticles offer great surface versatility, which in turn greatly expands the range of possible applications (imaging, energy, agritech, catalysis, environmental remediation, green chemistry, etc.).

Our services

Our services – Concept validation

SON can put its expertise in nanomaterials at your disposal to assist you with concept validation.

Whether you’re setting up a start-up or leading an innovative project, you need to validate the feasibility of your endeavour.

SON can help make it happen and assist you with your PoC (Proof of Concept).

Our services – Characterisation

SON provides a wide range of solutions for the analysis and characterisation of nanoproducts.

SON is able to rapidly detect the presence or absence of nanomaterials in a substance.

SON systematically authenticates the nanoparticles supplied to you against the expected specifications: size, shape, surface coverage rate, batch-to-batch consistency. Our precise, detailed analyses guarantee flawless results.

Our sophisticated technical platform means we can provide the right solutions for your needs.

Our services – Molecule grafting

With this technology, we’re able to provide solutions in molecular grafting that are unlike any others in the world.

SON is able to graft the molecules you need onto the surface of its advanced nanoparticles. These may include PEGs or treatments.

This lets you quickly confirm your hypotheses.
