| 英文摘要 | a simple label-free colorimetric sensor for sulfate has been devised based on the analyte-induced shielding of peroxidase-like activity of cysteamine-capped gold nanoparticles (cyst-aunps). aggregation triggered by sulfate through hydrogen bond and electrostatic interaction gave rise to a remarkable decrease of the catalytic activity of aunps. by coupling with 3,3',5,5'-tetramethylbenzidine (tmb)-h2o2 chromogenic reaction, a novel colorimetric sensor for detection of sulfate was established. based on the signal amplification effect of the catalytic reaction, a detection limit as low as 0.16 mu m was obtained by virtue of uv-vis spectroscopy or 4 mu m with the naked-eye observation. the as-proposed sensor exhibited an excellent selectivity over other common anions and metallic ions. in view of these characteristics, such sensing probe features simplicity, cost-effectiveness, and naked-eye screening. these advantages make this sensor a powerful protocol for the quantitative detection of sulfate in water samples with satisfactory results.
