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.

This article developed a resonance Rayleigh scattering technique-based sensing method for the detection of bentazone residual in water samples. This technique was carried out using chitosan-capped gold nanoparticles with spectrofluorimetric method. Because, Chitosan-capped AuNPs have exciting features, such as resonance Rayleigh scattering (RRS).
