What Are the Types of Optical Transducers in Nanotechnology?
There are several types of optical transducers employed in nanotechnology:
Photodetectors: Devices that convert light into electrical signals, commonly used in imaging and sensing applications. Fluorescent Sensors: Utilize the emission of light from a fluorophore upon excitation, useful for biological and chemical sensing. SPR Sensors: Rely on the resonance condition of surface plasmons to detect changes in the refractive index, widely used in biochemical assays. Quantum Dots: Semiconductor nanoparticles that exhibit size-dependent optical properties, utilized for high-sensitivity detection.
