Make the invisible visible,


Our Mission

Detect the presence of microbes before they create an infection


By making the invisible visible,

wherever needed and faster 

Bacteria, fungi, yeasts … microbes are invisible to the naked eye.

Present everywhere, in the environment or consumable goods, they can generate life-threatening infections. Nosocomial, septicemia, urinary, intestinal, pulmonary… infectious diseases account for nearly 17 million deaths a year worldwide, or about 1 in 3 deaths, this proportion can go up to 43% in developing countries. 

With Fast


And easy to use

Microorganisms detection solutions

Our technology

An unprecedented way of making microbian culture a quick identification and quantification method

Culture on a Petri dish, the Louis Pasteur’s method, has been the most effective way of identifying and counting microbes since the 19th century. Therefore this method is still the most often used today. Its principle : extracting the microorganisms from a sample, putting them on a dedicated Petri dish, containing the “food” they need to grow, then wait. Once the microbes have multiplied enough, they get visible to the eye, and can be counted. Though reliable, this method can take a lot of time, as some microbes need several hours to multiply.

The Diamidex technique : feeding microbes with a previously redisigned food…

Perfectly harmless for the microorganisms, Diamidexes patented Sugars have been especially designed for being eaten only by the targeted microorganisms. Once eaten, those Sugars make the microbes skins cover themselves with chemical hooks. Onto those hooks can then be plugged chemical objects, such as coloured, luminescent or fluorescent particles that can be seen at a very low concentration.

Microbes covered with those particles can become visible up to 10 times faster than with the traditional method.

Diamidex uses the metabolic and physical properties of living cells

to make the cells express themselves

A technology initiated from French academic excellence research, considered as a major scientific breakthrough

Our application domains

A 360° technological platform

dedicated to microbiological express  preventive diagnostic

Our goal is to allow the largest possible public to conduct preventing microbian testing wherever and whenever needed.

For that reason, we designed both testing procedures and dedicated equipment so they could be used by anyone (no technical skills required), anywhere : in laboratories or in the field with mobile and compact laboratories.

For water samples testing

(sanitary hot waters, potable waters, industrial cooling towers waters…)

For industrial goods samples testing
