Rapid diagnostic technologies (water, air, soil)

Application

Whether in liquid or gas media, the versatility of SENSOR 4.0 allows online process monitoring, contaminant or molecule of interest sensing , in many industrial sectors:

  • Food industry
  • Oil and gas
  • Biomedical / Pharmaceutical industry
  • Ecology & environment

Description

The sensor technology is based on a polymer cantilever micropatterned at the extremity of an optical fiber which allows high precision, selective, label free, and detection of a wide range of analytes The sensor provides a mass sensitivity of 2 Hz/ pg and a LOD of 10 ng/ml.

Receptor Element

Molecularly Imprinted Polymers
MIPs are biomimetic receptors capable of binding a target molecule with similar affinity and specificity to their natural counterparts

TRANSDUCER ELEMENT

Resonating polymer cantilever + Optical fiber
The target molecule changes the mass and varies the resonance frequency of the cantilever.
An optical signal is guided through the optical fiber and measures the frequency variation.

Advantages

  • In situ monitoring (results in realtime)
  • Multiplexing opportunity
  • Label free detection
  • Remote operation
  • Hundreds of analytes available to target
    • low molecular weight analytes
    • macromolecules such as proteins
  • Flexible use and integration in challenging environments
  • Easy system integration
