How to benchmark a SPR setup?

I have built my own SPR setup and I wanted to test the overall design. It essentially contains all the necessary SPR components like the laser, glass with gold coating, and a detector to capture...

Is there a way to couple light into fiber optic cable from the middle rather than the ends?

Many of the research papers I looked through have the laser or light source at one end of the fiber optic cable and a detector at the other end. But I wanted to know if there was any research on...

How to attach and remove coating from Surface Plasmon Resonance slide repeatedly?

The SPR slide is made of glass with a 50nm Au layer on top. Above this layer I can attach the streptavidin with one of the following procedures I found on another post for a bare glass slides: 1)...

What is the procedure for creating Surface Plasmon Resonance (SPR) slides out of plastic so that it can be rolled into a cylinder?

Typical SPR slides are made of glass with the 50nm gold coating on top. But I wanted to know how I could create SPR slides made from clear flexible plastic with the coating on top so that I can...
