What is the principle of SPRi?

Our technology measures modifications of the refractive index at the surface of the SPRi-Biochip, which can be correlated to mass variations. It can be used to detect interacting molecules in real time, to determine analyte concentration and to characterize the biomolecular affinity.

Dedicated surface chemistries allow ligand immobilisation on a flexible biochip in a multiplexed microarray format.

After injection of the sample solution, several hundreds different molecular interactions can be monitored in real time

SPR occurs when light interacts at the interface between the biochip’s metallic surface and the liquid medium
