Abstract
An overview of recent researches of surface plasmon resonance (SPR) sensing technology in Laboratory of Science and Technology of Micro-Nano Optics (LMNO), University of Science and Technology of China, is presented. Some novel SPR sensors, such as sensors based on metallic grating, metal-insulator-metal (MIM) nanoring and optical fiber, are designed or fabricated and tested. The sensor based on localized surface plasmon resonance (LSPR) of metallic nanoparticles is also be summarized. Because of the coupling of propagating surface plasmons and localized surface plasmons, the localized electromagnetic field is extremely enhanced, which is applied to surface-enhanced Raman scattering (SERS) and fluorenscence enhancement. Future prospects of SPR and/or LSPR sensing developments and applications are also discussed.
Highlights
Since the first application of surface plasmon resonance (SPR) phenomenon for gas detection and biologic sensor in 1982 [1], the SPR sensing technology has been widely used for the detection of biological and chemical analytes, environmental monitoring and medical diagnostics [2,3,4,5] in the past two decades.Surface plasmons (SPs) are coherent oscillations of free electrons at the boundaries between metal and dielectric which are often categorized into two classes: propagating surface plasmons (PSPs) and localized surface plasmons (LSPs) [6]
PSPs can be excited on the metallic films which have several approaches as the Kretschman [7] and Otto [8] prism coupler, optical waveguides coupler [9], diffraction gratings [10], and optical fiber coupler [11], whereas LSPs can be excited on metallic nano-particles, which both can induce a strong enhancement of electromagnetic filed in the near-field region, leading to a extensive application in surface-enhanced Raman scattering (SERS) [12], fluorescence enhancement [13], refractive index (RI) measurement [14], biomolecular interaction detection [15], and so on
We will review some recent works on SPR and localized surface plasmon resonance (LSPR) sensors at the Laboratory of Science and Technology of Micro-Nano Optics (LMNO) and make a prospect on the research and applications of SPR and LSPR sensors
