Study of localized surface-plasmon-resonance-based optical fiber sensor

Highly sensitive biochemical sensor comprising rectangular nanometal arrays

“…According to the physical properties of LSPR, a sensor is highly sensitive to changes in the analyte concentration when the analyte region contains numerous sites that can excite surface plasmons. Consequently, this characteristic enables the proposed sensor to exhibit high sensitivity [16][17][18][19][20][21]. According to mathematics, the obtained modes must be pairwise orthogonal; that is, the orthogonality of the modes must be 0.…”

“…Consequently, an LSPR sensor with no propagation capability features more resonance regions than does a PSPR sensor with propagation capability; this characteristic considerably increases the sensitivity of LSPR sensors to changes in target analytes [16][17][18][19][20][21]. Thus, LSPR sensors have been adopted in numerous fields including chemistry, biochemical sensing, label-free detection, and optoelectronics [22][23][24][25][26][27][28][29][30][31].…”

High-performance localized surface plasmon resonance fiber sensor based on nano-metal-gear array

“…These unique optical properties are widely exploited in various applications, ranging from chemical, biological sensing to subwavelength optical waveguides and surface-enhanced Raman scattering [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. The sensitivity of LSPR depends on the sizes and geometries of the nanostructures.…”

Size-Tunable Fabrication of Au Nanodot Arrays via Electrodeposition-Assisted Capillary Force Lithography

“…1 Among them, a signature optical property is known as the localized surface plasmon resonance (LSPR), which is created from collective oscillations of the conduction band electrons in metallic nanostructures when excited by incident light (electromagnetic radiation) at a specific wavelength. [2][3][4][5] Based on this LSPR property, significant attention has been given to the study of plasmonic properties and its development for potential applications, such as those found in optical devices, chemical/biological sensors, 6 7 solar cells, 8 9 and molecular rulers. 10 In the recent past, lots of attempts to fabricate periodic arrays of metallic nanostructures with narrow size distribution have been made since they can distinctly minimize the inhomogeneous broadening of LSPR responses.…”
