What is Environmental Monitoring?
Environmental monitoring involves the systematic collection and analysis of data concerning the quality of the environment. It aims to detect and measure pollutants, understand environmental changes, and ensure compliance with environmental regulations.
How Does Nanotechnology Enhance Environmental Monitoring?
Nanotechnology offers advanced tools and methods for environmental monitoring, enhancing sensitivity, specificity, and real-time data collection. Nanosensors can detect trace amounts of pollutants, providing early warnings and helping to mitigate environmental damage.
What are Nanosensors?
Nanosensors are devices that use nanomaterials to detect physical, chemical, or biological changes in the environment. They can be made from various materials like carbon nanotubes, metal oxides, and quantum dots, each offering unique properties tailored to specific monitoring needs.
