“…Firstly, unlike lamps and LEDs, lasers produce thin beams of light with photons moving in the same direction, and thus do not diminish in intensity as quickly as other light sources [43]. This allows for a longer distance covered between the light source and sample without losing excitation light intensity by the inversesquare law [44]. Furthermore, like LEDs, lasers offer a very small selection of wavelengths in the output beam, which negates the need for a monochromator which is necessary when using arc lamps [45].…”

Laser-induced fluorescence (LIF) has been a valuable analytical technique since the 1970s that has only been made more useful through advances in other scientific fields such as biochemistry. Moreover, advances in laser and detector technology have seen a decrease in LIF detector costs and an increase in their ease of use. These changes have allowed for LIF technology to be widely adopted for various sensor designs in combination with advanced instruments. With advances in biochemistry necessitating the detection of complex metabolites, labelling with fluorescent chemical reagents may be necessary to improve detection sensitivity. Furthermore, advances made in fluorescent labeling technologies have allowed for the use of LIF in the detection of nanoparticles as well as for imaging techniques using nanoparticles as signal amplifiers. This technology has become invaluable in the detection of environmental pollutants, monitoring of biological metabolites, biological imaging, and cancer diagnosis, making it one of the most valuable analytical science techniques currently available.
