Measure the antioxidant efficacy of your ingredients, your products
with an WEVA-ND test
What we offer at WAINVAM-E is to measure the antioxidant efficacy of your molecules, of your finished products, thanks to our advanced technology, based on the quantum properties of the NV centers of diamond.
Innovative
Thanks to the quantum technology of the NV centers of diamonds.
Reliable
Measurements are related to the quantum and structural properties of diamonds
Quantitative
Accurate and sensitive measurement of free radical concentration
Kinetic
Over several hours or even days: fluorescent sensors with NV centers are photostable and do not show photobleaching
Economical
A drop of sample is enough on the usual microscope supports (slides, multi-well plates, Petri dishes…)
The antioxidant efficacy measurement by WAINVAM-E is different from other measurements based on detection of coloured or fluorescent species, it can be applied to different fields
Measuring the antioxidant efficacy of an ingredient, a processed food, a food supplement, allows to ensure its shelf life, to improve its nutritional qualities, and to avoid the alteration of its taste, its texture and its visual aspect.
Measuring the antioxidant efficacy of an additive ensures that the final product will keep its properties (texture, visual aspect, mechanical resistance…) in spite of external aggressions (temperature, UV, air oxidation…).

results
Our technology allows us to accurately measure the average concentration of free radicals in real time and kinetically. The results obtained are as follows:
- The free radical concentration is compared before the use of antioxidants and after the addition of different samples (Figure 1)
- The concentration of free radicals is measured over time to visualise the kinetic reaction
The measurement is carried out
in several steps
Antioxidant molecules neutralise free radicals, which are molecules with a free electron and thus generate magnetic noise.
The magnetic species detection methods developed by WAINVAM-E make it possible to measure the concentration of these free radicals and to deduce the antioxidant efficacy.
Equipments used
Antioxidant efficacy measurement services are performed using WAINVIEW equipment:
Consumables used
We use nano-diamonds in solution to perform our tests.
We also offer a range of functionalised nano-diamonds and can expand this range as required.

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
