Abstract

In recent times, fluorescence-based analytical devices are getting more equipped with LEDs than conventional light sources because of their availability in a broad range of wavelengths and appropriate power outputs. Further, LEDs are compact and affordable compared to commonly used light sources. LEDs have played a key role in miniaturizing the fluorescence detection devices and bringing the instrument to the experiment, rather than vice versa. The current review summarizes the key factors in developing a sensitive, affordable, and portable LED-Induced Fluorescence (LED-IF) detection-based analytical devices and their applications in various fields. The first part of the review discuss the fundamental aspects of fluorescence as well as LEDs in general. Whereas, the second part highlights the technical considerations and the applications of sensitive LED-IF detection-based analytical devices.

摘要

最近，与传统光源相比，基于荧光的分析设备越来越多地配备 LED，因为 LED 具有广泛的波长范围和适当的功率输出。此外，与常用光源相比，LED 结构紧凑且价格合理。LED 在小型化荧光检测设备和将仪器用于实验方面发挥了关键作用，反之亦然。本综述总结了开发灵敏、经济、便携的 LED 诱导荧光​​ (LED-IF) 检测分析设备的关键因素及其在各个领域的应用。评论的第一部分讨论了荧光的基本方面以及一般的 LED。然而，
