Graphitic carbon nitride nanosheetG-quadruplex DNAzymeElectron transferBiomarkersHere we first reported that graphitic carbon nitride nanosheet (g-C3N4NS) could effectively quench the chemiluminescence (CL) of luminol-hydrogen peroxide (H2O2) system. According to the new discovery, a label-free and ...
Due to the excellent catalytic effect of g-C3N4–hemin and HGNPs on the luminol/H2O2ECL system, the as-prepared biosensor exhibited a good response performance to lactate with a linear range of 1.7 × 108to 5.0 × 104M and a detection limit of 5.5 × 109M. In addition, the prepared ...
Determination of lysozyme was achieved by releasing the luminol-labeled aptamer to generate achemiluminescence signal ata wavelength of 425nm. It was proved by experiments that the synthesized hemin@HKUST-1 had a strong catalytic effect on the luminol-NaOH-H2O2 system. Thechemiluminescence signal was ...
When THR existed, HG-DNAzyme was desorbed from the surface of T-Apt/SiO2@GO@CF and catalyzed the CL system of luminol-H2O2. Under optimized CL conditions, THR was measured with the linear concentration range of 1.5 x 10(-14) to 2.5 x 10(-11) moL/L and the detection limit of 6.3...

Once a sandwich immunocomplex is formed on the array, the tracing tag catalyzes the CL reaction of the luminol-p-iodophenol and H2O2 system to produce a CL signal, which is collected by a CCD camera. An intuitive CL image is obtained containing all of the spots on the array. Under ...
