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 H2O2 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 H2O2 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 H2O2 with a detection limit of 0.56 µM.

阿拉伯胶介导的银纳米粒子合成，用于比色和基于 SERS 的过氧化氢检测。

我们报告了一种合成阿拉伯树胶稳定银纳米粒子（GA-Ag NPs）的一步式绿色方法。合成的颗粒是单分散的，尺寸范围为15-20 nm。合成的银纳米颗粒用作比色传感器，用于检测 H2O2 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 H2O2 和人体血清样品中的葡萄糖。装饰在滤纸上的 GA-Ag NP 在检测 H2O2 时也表现出优异的 SERS 活性，检测限为 0.56 µM。
