Inhalt:
This work presents a simple evanescent wave sensing system, based on an interferometric approach, suitable to meet the demands on label free sensor systems for the detection of biomolecular interactions. A highly sensitive concept for detecting key-lock interactions of biomolecules in real time was set up. It was characterized using the system as a refractometer, and the proof of concept was verified by detecting the interaction of a 21-mer DNA fragment with the immobilized counterpart. This sensor system represents a basic concept towards high throughput application.
