'''Optical Sensors''' find applications in all sectors. They are used to detect luminous intensity, heat, presence, colour. Currently, most optical sensors are based on fibre optics or free space optics, but some new research deals with integrating sensor functions in photonic ICs. Plasmonics is a powerful technique for e.g molecular sensing. SPR-based sensing (Surface Plasmon Resonance) is a method that is both suitable and widespread in biotech labs for the ultra-sensitive detection of biochemical binding interactions of molecules to target structures tagged to a functionalised metallic surface. There is a need to standardise and control the sensitivity of photon-plasmon coupling. Specific chemical functionalisation of plasmonic nanostructures is one of the key challenges for application in the environmental monitoring and sensing field. | '''Optical Sensors''' find applications in all sectors.
