A Sensitive Signal-on Supersandwich DNA Biosensor Based on the Enhancement of Poly(aniline-luminol) Nanowires Electrochemiluminescence by Ferrocene

Electrochemiluminescence DNA Biosensor for HBV Based on Coralloid Poly(Aniline‐Luminol)‐MWCNTs and Catalysis of Ferrocene

“…Interestingly, an electrochemiluminescence imaging method based on polyluminol has been developed to display potential fingerprints, which is of great significance for criminal detection [12]. Polyaniline (PANI) has been paid much attention because of its high electrical conductivity, excellent biocompatibility and controllable nanostructures [13,14], and it has been used to copolymerized with luminol to develop ECL sensors [15,16]. The polyanilineluminol nanocomposites can offer superior specific surface area to facilitate biomolecule immobilization.…”

Electrochemical analysis based on bioaffinity

“…Li et al achieved a sensitive detection of aflatoxin B1 by regulating the ECL of Ru(bpy) 3 2+ by tuning the length of the DNA sequence between ferrocene and the luminophore of nitrogen-doped graphene quantum dots-Ru(bpy) 3 2+ -doped silica nanoparticles [ 16 ]. Ding et al reported a signal-on supersandwich-type DNA sensor based on the poly(aniline-luminol) nanowires (PALNWs) modified electrode and enhancement of ferrocene on the ECL of luminol [ 17 ]. Kitamura et al reported a unique nucleic acid sensing based on an electrochemical molecular beacon (eMB), fabricated by modifying both ends of stem-loop structured DNA with ferrocene and β-cyclodextrin as electrochemical signal generators and quenchers, respectively [ 18 ].…”
