Special Issue Information

Optical sensors are useful tools for detecting various target molecules with high sensitivity and selectivity even in complex sample matrix (e.g., saliva, serum, urine). As one of the leading optical sensing technologies, surface plasmon resonance sensors are well known for real time screening and monitoring analyte interactions. In recent years, the development of the fabrication and integration of nanostructures has boomed the design of the Surface Plasmon Resonance (SPR) sensors in a more effective and miniature way. Novel SPR sensors with different nanostructures—either as sensing substrate-like 2D materials (e.g., graphene) or signal amplification tags like gold nanoparticles—were reported. They have been demonstrated for applications including food and environment monitoring, clinical diagnostics/therapy, and homeland security protection. This Special Issue of Sensors will be dedicated to highlighting these emerging uses of SPR sensors, and presenting the latest technologies and methodologies developed in this interdisciplinary field of science. Topics include, but are not limited to, the following:

  • Optical design and systems for SPR sensing
  • Point-of-care SPR biosensors for theranostics
  • Theoretical analysis of physics and chemistry for SPR sensing
  • Proof-of-concept of sensing applications based on SPR
  • Case studies and data fusion of novel SPR sensors

Both reviews and original research papers are welcome.

Giant Goos-Hänchen Shifts in Au-ITO-TMDCs-Graphene Heterostructure and Its Potential for High Performance Sensor

In order to improve the performance of surface plasmon resonance (SPR) biosensor, the structure based on two-dimensional (2D) of graphene and transition metal dichalcogenides (TMDCs) are proposed to greatly enhance the Goos-Hänchen (GH) shift. It is theoretically proved that GH shift can be significantly enhanced in SPR structure coated with gold (Au)-indium tin oxide (ITO)-TMDCs-graphene heterostructure. In order to realize high GH shifts, the number of TMDCs and graphene layer are optimized. The highest GH shift (−801.7 λ) is obtained by Au-ITO-MoSe2-graphene hybrid structure with MoSe2 monolayer and graphene bilayer, respectively. By analyzing the GH variation, the index sensitivity of such configuration can reach as high as 8.02 × 105 λ/RIU, which is 293.24 times of the Au-ITO structure and 177.43 times of the Au-ITO-graphene structure. The proposed SPR biosensor can be widely used in the precision metrology and optical sensing. Full article
