摘要

本研究开发了一种基于共振瑞利散射技术的检测水样中苯达松残留量的传感方法。该技术是用荧光光谱法使用壳聚糖封端的金纳米粒子进行的。实验结果表明，所开发的方法可以检测浓度低至0.02的Bentazone残留 ng mL-1。总体结果证实了用于测量Bentazone的检测限非常低。将壳聚糖包覆的金纳米粒子作为一种优良的传感器应用于水样中苯达松的测定和分析。

Resonance Rayleigh scattering technique-using chitosan-capped gold nanoparticles, approaches spectrofluorimetric method for determination of Bentazone residual in water samples.

In this study, a resonance Rayleigh scattering technique-based sensing method for detecting Bentazone residual in water samples has been developed. This technique was carried out using chitosan-capped gold nanoparticles with a spectrofluorimetric method. Experimental results revealed that the developed method could allow the detection of Bentazone residual as low as a concentration of 0.02 ng mL^-1 within 50-sec time. Overall results confirmed the very low detection limit for measuring the Bentazone. The chitosan-capped gold nanoparticles as an excellent sensor were applied to measure and analyze Bentazone in water samples.
