“…Initial applications of SPR involved the investigation of optical properties inherent to thin metal films [1][2][3][4]. From these studies, SPR has expanded and is used in a variety of applications including absorbance measurements [5][6][7], bio-kinetic [8][9][10], bio-sensing [11,12], bulk liquid measurements [13], gas detection [14,15], immune sensing [16,17], light modulation [18], process analytics [19], spectrometers [20], SPR microscopy [21], refractive index measurements [22,23], SPR polarization fibers [24], and thin film characterization [21,25]. In addition to these applications, SPR has been used extensively in chemistry, theoretical physics, and experimental optics [26].…”
