What are the Types of Optical Sensors in Nanotechnology?
There are several types of optical sensors that benefit from nanotechnology, including:
Surface Plasmon Resonance (SPR) Sensors: Utilize the resonance of surface plasmons in metallic nanoparticles to detect changes in the local refractive index. Fluorescent Sensors: Employ quantum dots or other fluorescent nanomaterials to detect specific molecules through changes in fluorescence intensity. Raman Sensors: Enhance Raman scattering signals using nanostructures such as gold or silver nanoparticles.
