Luminescence sensors allow on-line monitoring of chemical species, biological components or physical parameters. In a sample, their luminescence properties show a measureable change in emission light intensity, emission wavelength (colour) or luminescence decay time. That allows detecting, quantifying and characterising a large variety of simple chemical parameters such as oxygen, ions, or pH-value, as well as highly complex biomolecules like enzymes, antibodies, DNA or lipids.
This contribution briefly demonstrates the principles and some applications of luminescence sensing of four analytes of significant importance to various fields: oxygen, pH-value, glucose and carbon dioxide.
