The comparison of LOD of some newly different developed luminol-based luminophores for analysis of H₂O₂.

ECL System	LoD and Notable Observations	Ref
Luminol immobilized on graphite as a paste electrode	0.7 × 10−8 μM; two nearly neutral samples spiked with 3% and 6% H2O2.	[176]
Luminol nitrogen doped GQDs	1 × 10−8 M; detection in water samples.	[185]
Luminol-H2O2; Flow injection analysis system with ECL detection	3.0 × 10−9 mol/L LoD equal to the level of CL; human serum samples.	[186]
Luminol based on synchronous dual sensitization of ECL by using TiNTs and platinum black.	66 pM (H2O2), 22 nM (resveratrol), and 30 nM (dopamine); human serum samples.	[187]
Luminol-based ECL system and fluorine-doped tin oxide making use of electrode modified with Au nanoparticles	8 nM; Living cell samples.	[188]
Luminol-capped AuNP-modified electrode	1 × 10−7 mol L−1	[189]
