“…[1][2][3][4][5] The immobilization of ECL reagents on solid supports has been an important subject for developing sensors, microchips, and portable detectors. [2,[6][7][8] In the past, much attention has been paid to the immobilization of tris(2,2'-bipyridyl)ruthenium(II) (TBR) and its derivatives, one of the most commonly used ECL reagents, because the organic bipyridyl group and the positive charge were helpful for the structural modification and immobilization and the ECL reagents are regenerable in ECL reactions.…”

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), the size of which depended on the amount of luminol. The morphology and surface state of as-prepared AuNPs were characterized by transmission electron microscopy, UV/visible spectroscopy, X-ray photoelectron spectroscopy, FTIR spectroscopy, and thermogravimetric analysis. All results indicated that residual luminol and its oxidation product 3-aminophthalate coexisted on the surface of AuNPs through the weak covalent interaction between gold and nitrogen atoms in their amino groups. Subsequently, a luminol-capped AuNP-modified electrode was fabricated by the immobilization of AuNPs on a gold electrode by virtue of cysteine molecules and then immersion in a luminol solution. The modified electrode was characterized by cyclic voltammetry, electrochemical impedance spectroscopy, and scanning electron microscopy. The as-prepared modified electrode exhibited an electrochemiluminescence (ECL) response in alkaline aqueous solution under a double-step potential. H2O2 was found to enhance the ECL. On this basis, an ECL sensor for the detection of H2O2 was developed. The method is simple, fast, and reagent free. It is applicable to the determination of H2O2 in the range of 3x10(-7)-1x10(-3) mol L(-1) with a detection limit of 1x10(-7) mol L(-1) (S/N=3).

“…Some papers reported the determination of CA with CL [34][35][36][37][38] and electrochemiluminescence techniques (ECL). [39][40][41][42] But there are much fewer studies on the HPLC-CL joint technique applied to detection of CA. 43,44 Both of the groups used postcolumn fluorogenic derivatization with peroxyoxalate CL detection.…”

A simple, rapid and accurate high performance liquid chromatographic (HPLC) technique coupled with chemiluminescence (CL) detection was developed for the simultaneous determination of epinephrine (E), noradrenaline (NA) and dopamine (DA). It was based on the analyte enhancement effect on the CL reaction between luminol and potassium ferricyanide. The effects of various parameters, such as potassium ferricyanide concentration, luminol concentration, pH value and component of the mobile phase on chromatographic behaviors of the analytes (E, NA and DA) were investigated. The separation was carried out on C 18 column using the mobile phase of 0.01 mol/L potassium hydrogen phthalate solution and methanol (92∶8, V/V). Under the optimum conditions, E, NA and DA showed good linear relationships in the range of 1×10 -8 -5×10 -6 , 5.0×10 -9 -1.0×10-6and 5.0×10 -9 -1.0×10 -6 g/mL respectively. The detection limits for E, NA and DA were 4.0×10 -9 , 1.0×10and 8.0×10 -10 g/mL. The proposed method has been applied successfully to the analysis of E, NA and DA in human serum samples.

“…Chemiluminescence has also been applied to determine DPH; however, some chemiluminescence reactions have hardly found extensive applications due to the instability of the oxidation reagents. [11][12][13] Spectrophotometry 14 was also used to determine DPH, and the apparent molar absorption coefficients of determination of DPH were 6.47 × 10 3 and 7.4 × 10 3 L mol -1 cm -1 , respectively. However, the apparent molar absorption coefficient of DPH was found to be 3.2 × 10 4 L mol -1 cm -1 by this proposed method.…”
