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

Quantum physics practical work with WAINTEACH
1. Spin resonance and Zeeman effect The NV centre of a diamond has an electron spin S=1. Therefore, three fine levels can be distinguished, corresponding to the projection of the spin on the axis of the NV centre, |𝑚_𝑠=0, ±1⟩. When illuminated with a green
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
The operation of a NV magnetometer
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 properties
