Abstract: Light can be used to spatially resolve electrochemical measurements on a semiconductor electrode. This phenomenon has been explored to detect DNA hybridization with light-addressable potentiometric sensors and, more recently, with light-addressable erometric sensors based on organic-monolayer-protected Si(100). Here, a contribution to the field is presented by comparing sensing performances when bovine serum albumin (BSA) and hexaethylene glycol (OEG

Abstract: The CL intensity of luminol-diperiodatoargentate(III) (DPA) system is strongly enhanced by addition of iron nanoparticles (FeNPs) covered with C12E4. On injection of aminophylline into luminol-DPA-FeNPs system, the CL intensity is significantly increased. On this basis, a sensitive CL assay was developed for determination of AmP in human serum. FeNPs could catalyze the oxidation rate of luminol in the present of oxygen. Also, the CL intensity of luminol-DPA-FeNPs system is significantly increased in the presence of aminophylline (AmP). Based on this ruling, a sensitive CL assay was developed for determination of AmP in human serum. The influences of analytical variables on the CL signal were studied and optimized. Under the optimum conditions in the present of FeNPs, the CL intensity is linearly increased with AmP concentration in the range of 1.0×10(-8)-2.0×10(-6) mol L(-1). The detection limit was 9.8×10(-9) mol L(-1) AmP and the relative standard deviation for ten parallel measurements of 8.0×10(-7)mol L(-1) AmP was also 4.8%. The proposed system was successfully applied to determine AmP in human serum s les.

Abstract: Colloidals solution of Fe3 O4 magnetic nanoparticles (MNPs), capped with β-cyclodextrins (β-CD) as inclusion complexes, were found to enhance the chemiluminescence (CL) intensity of the luminol-diperiodatoargentate(III) (DPA) system. On injection of cysteine into the luminol-DPA-β-CD-Fe3 O4 MNPs inclusion complexes system, the CL intensity is strongly enhanced. The enhanced CL signal is ascribed to the catalytic effect of Fe3 O4 MNPs capped with β-CD, which is assumed to stabilize the CL intermediate. Based on these findings, a rapid and sensitive assay was developed for the determination of cysteine in human serum. The effects of analytical variables on the CL signal were studied and optimized. Under the optimum conditions, the CL intensity was directly proportional to the concentration of cysteine in the range 8.0 × 10(-9) -1.0 × 10(-6) mol/L. The detection limit was 2.8 × 10(-9) mol/L (3 S(b) /m) and the relative standard deviation (RSD) for 10 replicate determinations of 1.0 × 10(-7) mol/L cysteine was 3.5%. The proposed method was applied to the sensitive determination of cysteine in human serum s les, and compared with the Ellman method with satisfactory results.
