Study of highly stable electrochemiluminescence from [Ru(bpy)3]2+/dicyclohexylamine and its application in visualizing sebaceous fingerprint

For the first time, we report a novel and highly stable visual electrochemiluminescence emission from the [Ru(bpy)(3)](2+)/dicyclohexylamine system at physiological pH conditions, with a quantum efficiency (phi(ECL)) of 95.5%. Furthermore, we have successfully demonstrated the simple and rapid smartphone-based ECL mapping of sebaceous fingerprints via a non-destructive mode.

Automated summary

This study reports for the first time a novel and highly stable visual electrochemiluminescence emission system at physiological pH conditions, with a high quantum efficiency. Furthermore, a simple and rapid smartphone-based non-destructive mode for sebaceous fingerprint electrochemiluminescence mapping has been successfully demonstrated.
