chemical detection

Chemical detection involves identifying the presence of specific chemicals in a sample through specialized sensors or tests. These sensors recognize molecules based on their unique properties, such as electrical signals, color changes, or other physical responses. For example, a breathalyzer detects alcohol by sensing chemical compounds in breath, while environmental tests might use reactive strips to identify pollutants. This process is vital for safety, health, and environmental monitoring, providing accurate information about chemical composition quickly and reliably without needing complex laboratory equipment.
