Fluorescence-based sensors

Fluorescence-based sensors detect specific substances by using substances that emit light when exposed to a particular type of energy, like UV light. These sensors contain materials that "glow" or fluoresce only in the presence of certain chemicals or biological markers. When the target substance binds or interacts with the sensor, it causes a change in the fluorescence signal, which is measured to identify or quantify the substance. This method allows for highly sensitive, rapid, and specific detection of various analytes in fields like medical diagnostics, environmental monitoring, and food safety.
