Gold colloids with nanoparticles of different sizes were found to enhance the chemiluminescence (CL) luminol-H2O2 system, and most intensive CL signals obtained 38-nm-diameter gold nanoparticles. UV-visible spectra, X-ray photoelectron transmission electron microscopy studies carried out before after reaction investigate enhancement mechanism. The by system was supposed originate from catalysis nanoparticles, which facilitated radical generation electron-transfer processes taking place on...
In this communication, we report a general strategy for the production of carbon nanodots (CDs) by microwave irradiation amino acids in presence acid or alkali. The resultant CDs exhibit strong photoluminescence and intense chemiluminescence enhancement NaIO(4)-H(2)O(2) system.
The electrochemiluminescence (ECL) behavior of luminol on a gold nanoparticle self-assembled electrode in neutral and alkaline pH conditions was studied under conventional cyclic voltammetry (CV). exhibited excellent electrocatalytic property redox reactivity to the ECL system. In solution, four peaks were observed at 0.69, 1.03, -0.45, -1.22 V (vs SCE) curve intensity versus potential. Compared with bulk electrode, two anodic one cathodic greatly enhanced, new peak appeared. obtained 0.69...
Carboxylic acid- and amino-functionalized ionic liquids were used as the stabilizer for systhesis of metal nanoparticles in aqueous solution. Smaller gold (3.5 nm) platinum (2.5 prepared with NaBH4 reductant.

It was found that chloroauric acid (HAuCl(4)) could be directly reduced by the luminescent reagent luminol in aqueous solution to form gold nanoparticles (AuNPs), size of which depended on amount luminol. The morphology and surface state as-prepared AuNPs were characterized transmission electron microscopy, UV/visible spectroscopy, X-ray photoelectron FTIR thermogravimetric analysis. All results indicated residual its oxidation product 3-aminophthalate coexisted through weak covalent...
Ratiometric electrochemiluminescence (ECL) has attracted special focus in the biological analysis field, because it could eliminate environmental interference and allow for precise measurement. Herein, a dual-wavelength ratiometric ECL biosensor was designed detection of cardiac troponin I (cTnI), where (4,4′-dicarboxylic acid-2,2′-bipyridyl) ruthenium(II) (Ru(dcbpy)32+) Au nanoparticle-loaded graphene oxide/polyethylenimine (GPRu–Au) nanomaterial acts as an acceptor, nanoparticle-modified...
Recently, nanoluminophores with the potential-resolved multicolor electrochemiluminescence (PRMCECL) property have emerged and shown promising applications in sensitive, selective, accurate bioassays, bioimaging, emitting devices. However, only limited PRMCECL their ratiometric biosensors eliminating proportional errors been reported. Herein, a novel nanoluminophore was synthesized by encapsulating CdS quantum dots (CdSQDs) into MOF-5 (CdSQDs@MOF-5). Using K2S2O8 as coreactant, two (ECL)...
Most known chemiluminescence (CL) reactions exhibit flash-type light emission. Great efforts have been devoted to the development of CL systems that emit with high intensity and long-lasting time.
