Abstract
A sensor is a device capable of continuously monitoring a physical parameter or the concentration of an analyte. Among the various types of sensors, electrochemical and optical sensors form the two largest groups. Optical sensors (“optrodes” or “optodes”) are mainly based on the detection of changes in absorbance, reflectance, fluorescence or chemiluminescence. But also Raman-scattering, refractive index, light polarization, light scattering and other optical properties have been used as analytical parameters.
