The fluorescent probes play an important part in the field of food safe and biological chemistry due to their high sensitivity, fast response time and technical simplicity. Under the conditions of analysis associated with the targeted analyte, the fluorescence sensing systems are able to provide a reliable fluorescence response in the field chemical, environment and biological.
In generally, most of the fluorescent probes consist of fluorophore, space and receptor. According to the receptor, the detection principle of fluorescent probes can be divided into the fluorescent resonance energy transfer (FRET), intra-molecular charge transfer (ICT), photoinduced electron transfer (PET) and excited-state intramolecular proton transfer (ESIPT). It is worth noting that the fluorescent probes not only contain a kind of detection principle, and may contain two or more kinds of detection principle.
Fluorescent probes are easily affected by the surrounding environment during detection. These factors include viscosity, solvent polarity, temperature, pH and oxygen.
