We report on the one-step green method to synthesize Gum Arabic stabilized silver nanoparticles (GA-Ag NPs). The synthesized particles are monodispersed and in the size range of 15-20 nm. The synthesized Ag NPs are used as a colorimetric sensor for the detection of HO and glucose with a detection limit of 11.7 nM and 0.13 µM, respectively. The sensor has also been used for the detection of HO in water samples and glucose in human blood serum samples. The GA-Ag NPs decorated on filter paper have also shown excellent SERS activity for the detection of HO with a detection limit of 0.56 µM.
我们报道了一种一步绿色合成阿拉伯胶稳定的银纳米颗粒（GA-Ag NPs）的方法。合成的颗粒呈单分散状态，尺寸范围为15 - 20纳米。合成的Ag NPs用作比色传感器，用于检测过氧化氢（HO）和葡萄糖，检测限分别为11.7 nM和0.13 μM。该传感器还用于检测水样中的HO和人血清样品中的葡萄糖。装饰在滤纸上的GA-Ag NPs对HO的检测也显示出优异的表面增强拉曼散射（SERS）活性，检测限为0.56 μM。
