Electrochemiluminescence Immunosensor Based On Platinum Nanoparticles For The Determination Of Apolipoprotein A1, Liao Ni, Zhuo Ying, Yuan Ruo
Journal of Electrochemistry
In this paper, a novel electrochemiluminescence (ECL) immunosensor for the detection of apolipoprotein A1 was constructed based on flower-like platinum nanoparticles (PtNFs) via a one-pot chemical synthesis method. The PtNFs was used to immobilize the secondary antibody and enzyme (GOD). Then the prepared bioconjugates were introduced onto the electrode via sandwich immunoreactions. Accordingly, the ECL luminophore peroxydisulfate (S2O82- ) was presented in the working buffer solution containing an appropriate amount of glucose. Through the ECL responses of S2O82- and O2, a dramatically amplified ECL signal was obtained for the reason …
