我们提出了一种新的方法,使同时合成和沉积的金微花(AuMFs)在固体基底上的一锅法,使用两种试剂,金酸和盐酸羟胺,在水性反应混合物。沉积在基底上的AuMF形成机械稳定的扩展纳米结构表面的金层。AuMF的形态取决于反应溶液的组成以及反应时间,并且可以通过反应溶液的组成以及反应时间来控制。我们的方法获得的纳米结构的金属层被用作有效的平台,化学和生物传感的基础上表面增强拉曼光谱(Sers)。对巯基苯甲酸和λ噬菌体的Sers光谱记录的这样的平台表现出超过106的增强因子和良好的再现性。
We present a new method enabling simultaneous synthesis and deposition of gold micro-flowers (AuMFs) on solid substrates in a one-pot process that uses two reagents, auric acid and hydroxylamine hydrochloride, in aqueous reaction mixture. The AuMFs deposited onto the substrate form mechanically stable gold layer of expanded nanostructured surface. The morphology of the AuMFs depends on and can be controlled by the composition of the reaction solution as well as by the reaction time. The nanostructured metallic layers obtained with our method are employed as efficient platforms for chemical and biological sensing based on surface-enhanced Raman spectroscopy (SERS). SERS spectra recorded by such platforms for p-mercaptobenzoic acid and phage lambda exhibit enhancement factors above 106 and excellent reproducibility.
