An introduction to surface plasmon resonance

Surface plasmon resonance (SPR) is a real-time, label-free optical technique used to detect and quantify molecular interactions. SPR has important applications in drug discovery and development and has many advantages over end-point analysis techniques, such as ELISA, which have made it an attractive tool for analyzing molecular interactions.

But how does this phenomenon work, and what are its applications?
