Abstract
Recent Advances in Surface Plasmon Resonance Optical Sensors for Potential Application in Environmental Monitoring
Highlights
Optical sensors are known to be among the most versatile sensing tools, with the ability to detect a wide range of targets such as temperature, pressure, radiation level, force, electric field, pH, strain, chemical concentration, displacement, liquid level, displacement, humidity, magnetic field, acoustic field, and many more
The results showed that there was no appreciable influence on selectivity even when the interferents had a 10-fold higher concentration.[87]. Table 3 shows all the active layers of Surface plasmon resonance (SPR) optical sensors used for the detection of insecticides such as chlorpyrifos, dimethoate, carbofuran, carbendazim, and fenitrothion in chronological order
This paper has reviewed recent trends in SPR optical sensors for the potential sensing of environmental pollutants
Summary
Optical sensors are known to be among the most versatile sensing tools, with the ability to detect a wide range of targets such as temperature, pressure, radiation level, force, electric field, pH, strain, chemical concentration, displacement, liquid level, displacement, humidity, magnetic field, acoustic field, and many more. The Kretschmann configuration is the most common setup used for SPR optical sensors In this configuration, monochromatic and p-polarized light is used to form a surface plasmon that propagates along a metal surface. An SPR optical sensor works by measuring the refractive index near the metal surface. Over the past two decades, research has been carried out to improve the sensitivity of SPR sensors for sensing applications either by the modification of the SPR system or by combination with various sensing methods.[3,4,5,6,7,8] Another approach has been to modify the metal thin film surface with an active layer or a sensing element. The detection limit, sensitivity, and selectivity of these active layers in combination with SPR sensing for environmental pollutants have been reviewed and summarized
