Abstract

A new nanocomposite material based on gold nanorods and polyurethane foam was obtained, and a method for the determination of catecholamines with the use of this nanocomposite modified with silver nitrate was developed. The determination is based on the measuring hypsochromic shift of a short-wave surface plasmon resonance band in a diffuse reflection spectrum of the nanocomposite. This shift is caused by reduction of silver from silver ions on the surface of gold nanorods under the influence of catecholamines. Effects of time, pH, volume of the reaction mixture, concentration of silver ions, and catecholamines on the interaction were examined. The proposed method allows to determine dobutamine, epinephrine, norepinephrine and dopamine with the detection limits of 0.1, 0.07, 0.07, and 0.05 μg mL^?1, respectively. The developed method can be applied to analysis of medicines.

一种基于聚氨酯泡沫和金纳米棒的新型固相光谱测定儿茶酚胺的纳米复合光学传感器

制备了一种基于金纳米棒和聚氨酯泡沫的新型纳米复合材料，并建立了一种用硝酸银修饰的纳米复合材料测定儿茶酚胺的方法。通过测量纳米复合材料漫反射光谱中短波表面等离子体共振带的次色移来确定。这种转变是由于在儿茶酚胺的作用下，金纳米棒表面的银离子中银的还原引起的。考察了反应时间、pH、反应混合物体积、银离子浓度和儿茶酚胺对反应相互作用的影响。该方法可测定多巴酚丁胺、肾上腺素、去甲肾上腺素和多巴胺，检出限分别为0.1、0.07、0.07和0.05 μ mL?1,分别。该方法可用于药物的分析。
