Recent trend in the nanotechnology made an interest to make nano based system to detect the environmental pollutant including heavy metals, pesticides and antibiotics. Mercury is toxic heavy metals which causes hazardous effect to human and environmental organisms. They usually reach to the environment by mining, petrol refining and coal burning, which can change to its ionic forms according to the environmental condition. The present study was concentrated on the effective detection of Hg (II) ion from environmental sample colorimetrically by developing Ag NPs - tryptophan nanoconjugate functionalized with 3-(Trimethoxysilyl)propyl methacrylate (TMPM). The characterization of prepared particles was performed by UV-visible spectrophotometer, transmission electron microscopy (HRTEM), Fourier-transform infrared spectroscopy (FTIR), X-ray diffractometer (XRD), particle size analyzer and zeta sizer. The size of prepared NPs was 9 ± 1.10 nm and it possess the surface charge of -37.41 ± 4 mV. Upon the interaction of Ag NPs - tryptophan nanoconjugate and Hg (II) ion, the colour of the conjugate disappeared. The effect of environmental factors (Temperature, pH and saline concentration) on Hg (II) ion detection was also investigated. The probe indicated that Ag NPs - tryptophan nanoconjugate functionalized with TMPM was found to be an efficient tool for mercury detection from various environmental water samples.

使用3-（三甲氧基甲硅烷基）丙基甲基丙烯酸酯功能化的Ag NPs-色氨酸纳米共轭物比色检测环境水样中的汞离子。
纳米技术的最新趋势使制造基于纳米的系统以检测包括重金属，农药和抗生素在内的环境污染物引起了人们的兴趣。汞是有毒的重金属，会对人体和环境生物造成危害。它们通常通过采矿，汽油精炼和燃煤达到环境，这些环境可以根据环境条件转变成离子形式。本研究集中在通过开发Ag NPs-用甲基丙烯酸3-（三甲氧基甲硅烷基）丙酯功能化的色氨酸纳米共轭物来比色法从环境样品中有效检测Hg（II）离子。制备的颗粒的表征通过紫外可见分光光度计，透射电子显微镜（HRTEM），傅里叶变换红外光谱（FTIR），X射线衍射仪（XRD），粒度分析仪和Zeta分级仪。制备的NP的大小为9±1.10 nm，表面电荷为-37.41±4 mV。在Ag NPs-色氨酸纳米缀合物和Hg（II）离子相互作用后，缀合物的颜色消失。还研究了环境因素（温度，pH和盐浓度）对Hg（II）离子检测的影响。该探针表明，用TMPM功能化的Ag NPs-色氨酸纳米共轭物是从各种环境水样中检测汞的有效工具。还研究了环境因素（温度，pH和盐浓度）对Hg（II）离子检测的影响。该探针表明，用TMPM功能化的Ag NPs-色氨酸纳米共轭物是从各种环境水样中检测汞的有效工具。还研究了环境因素（温度，pH和盐浓度）对Hg（II）离子检测的影响。该探针表明，用TMPM功能化的Ag NPs-色氨酸纳米共轭物是从各种环境水样中检测汞的有效工具。
