Several types of nanosensors are utilized across various fields:
1. Electrochemical Nanosensors: These sensors detect changes in electrical properties due to chemical reactions. They are widely used for detecting biomolecules and toxins.
2. Optical Nanosensors: These sensors rely on changes in optical properties, such as fluorescence or absorbance, to detect analytes. They are useful in biosensing and environmental monitoring.
3. Mechanical Nanosensors: These sensors measure changes in mechanical properties, like mass or stiffness. They are often used in MEMS and NEMS devices for detecting physical forces and masses at the nanoscale.
