Why performing imaging?

Imaging allows monitoring simultaneously the resonance conditions on the whole surface of the SPRi-Biochip. If the SPRi-Biochip contains different immobilized molecules (array format), potential interactions on those different molecules (also called ligands or spots) are monitored in parallel thanks to the use of a CCD camera. This property (simultaneous measurement on all the elements of the microarray) is also often referred as multiplexing.

The imaging feature of our devices enables the multiplex measurement of up to several hundred interactions.

The flow cell image retrieved by the software corresponds to the real time image of the SPRi-Biochip surface. The difference image shows interacting spots when the analyte solution is injected.
