What Are the Types of Nanotechnology-Based Detectors?
Nanotechnology-based detectors can be broadly classified into several categories:
Optical Detectors: Utilize the optical properties of nanomaterials to detect changes in light absorption, emission, or scattering. Examples include surface plasmon resonance sensors and fluorescent nanoparticle-based detectors. Electrochemical Detectors: Employ nanomaterials to enhance the electrochemical signal of target molecules. These detectors are commonly used in biosensors for detecting glucose, DNA, and other biomolecules. Mechanical Detectors: Rely on the mechanical properties of nanomaterials, such as nanowires and cantilevers, to detect physical changes like mass or force variations.
