Surface plasmon resonance technology: Recent advances, applications and experimental cases

In the modern era of advanced technologies, rapid and accurate analyses are needed, both for scientific research and for industrial applications. For this reason, the Surface Plasmon Resonance (SPR) technology emerged as very successful particularly in the last ten years, being capable of measuring interactions in real time with high sensitivity and without the need for labels. Thanks to these characteristics, SPR has gained great popularity and represents a viable choice for many applications, from life sciences to pharmaceutics, agrifood and environmental monitoring of harmful substances. Herein, we examine the recent advances in the development of SPR technology to provide an excursus on the various types of instrumentation available on the market, discuss their advantages and their limitations as well as future trends, and to analyze particular case studies addressed by SPR technology.
