Review of Fluorophores based on Fluorescence Resonance energy Transfer as Sensing Application

Dhaidan Khalaf Kafi


Fluorescence resonance energy transfer (FRET) has a wide range of uses and has become a standard technique in many biological and biophysical domains during the past 25 years. For this reason, it has become necessary to know the methods and materials used in this field. Light radiation leads to the proper wavelength leading to electronic excitement in a pigment particle. This excitement subsides after a while if there are no other pigment particles nearby. Nevertheless, if the other pigment particles are only little nanometers apart, they can transmit excitation power. In a few years, Förster Resonance energy Transmission (FRET) has been used as a potent implement to supply information about many applications of biosensing and bioanalysis. Numerous innovative chemical sensors and biosensors have been developed based on the FRET process. This review focuses on the most current uses for sensitive and selectiveyratiometric FRET-based sensors.
