WELFA test kits

(WAINVAM-E Lateral Flow Assay)

the WELFA test kits

WELFA is a new generation of ultrasensitive rapid diagnostic test that combines the principle of lateral flow immunoassay (LFIA) with the unique optical properties of NV nano-diamonds.
WAINVAM-E functionalises NV nano-diamonds by attaching antibodies directed to a biomolecule of interest. As the nano-diamonds emit red fluorescence when irradiated with a green laser, they are then transformed into a fluorescent probe or marker capable of recognising molecules of interest in a targeted and selective manner.

Detection and measurement

The kit allows the rapid detection and measurement of biomarkers of inflammation, cancer, infection etc. for early diagnosis and better patient management.

Detection and identification

It detects and identifies toxins, allergens, pesticides, pathogens, illegal ingredients and for Quality Control along the production line.


The determination of biomarker groups in R&D is in its pre-clinical and clinical studies.

  • Functionalised nano-diamonds in solution
  • Tape, containing a functionalised strip

The WELFA detection device developed by WAINVAM-E modulates the intensity of the fluorescence emission of the nano-diamonds. This allows the signal emitted by the nano-diamonds to be separated from the fluorescence background and therefore allows very low levels of biomarkers to be specifically detected.

WAINVAM-E proposes to develop your own WELFA Kits according to your target:
  • The analytes to be detected, their quantification
  • The matrices to be analysed (blood, urine, saliva, media …)
  • The expected measurements and performances

This kit is intended

Quantum sensors

A quantum revolution 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

Oxidative stress

Oxidative stress Oxidative stress is involved in many phenomena ranging from a simple burn to serious diseases such as cancer, infectious and neurodegenerative diseases. Accordingly, the reliable, accurate and sensitive detection of oxidative stress in cells as proposed by WAINVAM-E enables many medical diagnostics. It

The functioning of a NV magnetometer

Magnetometry Magnetometry refers to the general principle of measuring the magnetic field of a system in order to study or characterise certain properties. The sensor with which magnetometry measurements are made is called a magnetometer. At WAINVAM-E we develop magnetometers using the optical and quantum

Functionalisation of nano-diamonds

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
