摘要：
We developed an extensible LED-induced fluorescence detection module with a highly integrated and ultra-compact structure. A target-oriented design methodology was used to demonstrate the module’s optimal design. Lucigenin solution was used as a test sample in evaluation trials to demonstrate the module’s quantitative fluorescence detection capability. Results showed that the integrated module has an outstanding linear response in the range of 0–1 µmol·L−1, with sensitivity and limit of detection (LOD) of 0.1692 V/µmol·L−1 and 0.03 µmol·L−1, respectively. Statistical analyses showed that our integrated module has extremely high repeatability and accuracy, i.e., the values of Pearson’s correlation coefficient and root-mean-square error exceeded 0.9995 and 1.8‰, respectively. More importantly, the integrated module possesses favorable extensibility and can realize on-demand rapid fluorescence-signal detection of other targets using appropriate parameter combinations. This module offers new opportunities for reliable, cost-effective and easy-to-use fluorescence-signal detection, especially in resource-constrained fluorescence detection applications.
