With the world wildly improvement in dietary and nutrition status, it couldn't be ignored that the chronic liver disease (CLD) resulted from the overnutrition. In order to estimate nutrition status for healthy living, an efficient and sensitive electrochemiluminescence (ECL) sandwich immunosensor of laminin (LN), a marker of CLD, was proposed for early diagnosis of CLD. In this work, the anodic ECL behavior of perylene derivative using H2O2 as co-reactant was demonstrated and the possible ECL mechanism was proposed. Furthermore, a significantly amplified ECL response could be obtained via Ag and Fe-Fe2O3 nanoparticles as bis-co-reaction accelerator. As a result, the proposed ECL immunosensor performed good sensitivity and accuracy with a detection limit down to 0.03pg/mL. Moreover, this immunosensor was successfully employed to monitor patient serum, which exhibited an alternative avenue for the early diagnosis of other diseases via proteins, nucleotide sequence, microRNA and cells.
