- •
We report an angle-scanning optical surface-plasmon-resonance (SPR) based biosensor designed with a laser line generator.
- •
The laser beam is only driven to scan automatically on the surface of the biosensor while the area CCD camera is fixed without moving.
- •
It is capable to detect a change in the refractive index of the ethanol solution with the relative high linearity at the correlation coefficient of 0.9842.
- •
The expanded detection range could be achieved effectively.
