Measuring the antioxidant efficacy of your ingredients and products
Antioxidants, whether they are naturally present in a product or added during its manufacture, help to protect it against damage caused by time, UV rays, pollution, etc., and thus increase its lifespan.
Many methods are available on the market, including ORAC, FRAP, DPPH tests, which we offer to perform for you.
They are not always easy to implement and only quantify certain free radicals. In addition, various techniques are pH-dependent, making it difficult to take measurements.
In response to this, WAINVAM-E develops an innovative method WEVA-ND based on the use of nano-diamonds with NV centers (Nitrogen-Vacancy). Nano-diamonds are time-stable elements that allow an infinite kinetic measurement while ensuring an accurate, sensitive and quantitative antioxidant evaluation.
This technology will allow us to perform an antioxidant evaluation of your samples in many fields such as in the food industry to monitor the oxidation of a vegetable oil.

Quantum sensors
A quantum sensor is a measuring instrument that exploits the laws of quantum mechanics and provides the measurement of physical quantities directly from values of fundamental constants of quantum physics. Such a sensor is therefore inherently accurate and stable, both being essential properties for many
Oxidative stress
Oxidative stress is involved in many phenomena ranging from a simple burn to serious diseases such as cancer, infectious diseases or neurodegenerative diseases. It is promoted by internal mechanisms such as infections or deficiencies, as well as by external factors such as smoking, sun exposure
Functionalisation of nano-diamonds
The functionalisation of nano-diamonds refers to the modification of their surface that includes binding with chemicals or biomolecules (acids, proteins, etc.) to improve their properties and to bind them to specifically targeted locations with high precision [1,2]. Why is the functionalisation of nano-diamonds necessary? The
Metrology
Metrology is the science of measurement. It defines the units of measurement, realises them, maintains their integrity, disseminates them and regularly leads to improvements in the international system of units. National metrology bodies serve as reference points for the calibration of measuring instruments used in
