This Perspective discusses recent advances in the field of surface plasmon resonance imaging (SPRi) for the label-free, multiplex, and sensitive study of biomolecular systems. Large efforts have been made during the past decade with the aim of developing even more sensitive and specific SPRi-based platforms. Metal nanostructures have been used to enhance SPRi sensitivity and to build a specific SPR-active surface, while special effects such as long-range SPR have been investigated to develop more effective SPRi platforms. Here, we review some of the significant work performed with SPRi for the ultrasensitive detection of biomolecular systems and provide a perspective on the challenges that need to be overcome to enable the wide use of SPRi in emerging key areas such as health diagnostics and antidoping controls.
