Modern surface plasmon resonance for bioanalytics and biophysics.

Physical chemistry, materials science, analytical chemistry and engineering greatly contributed to the increasing popularity of bioanalytical and biophysical applications of surface plasmon resonance (SPR) by providing novel materials, surface chemistry, instrumental concepts, and theory to further understand the plasmonic phenomenon and support innovation in SPR. This perspective article portrays the contemporary state of SPR-based techniques and establishes a list of challenges to be overcome for improving bioanalytical and biophysical applications of plasmonics and surface plasmon resonance.
