| 摘 要： | 采用种子生长法制备Au纳米棒(GNRs),随后进行组装和煅烧得到单层致密堆积的GNRs薄膜。在煅烧过程中,组装所需有机物在煅烧过程中分解,从而使得GNRs表面具有较高的清洁度。研究中发现,煅烧前后金纳米棒表面的间隙进一步提高,增强了其SERS(表面增强拉曼光谱)活性。为了研究其SERS活性,选择了2种探针分子以研究其灵敏度和均匀性,发现其具有较高的灵敏度和高的信号稳定性。随后将所制备的SERS基底成功用于检测超低浓度的农药分子。

| Abstract: | A monolayer close-packed Au nanorods (GNRs) film has been prepared by an easy seed-growth approach, followed by self-assembling method with the surfactants and subsequent calcination treatment. During the calcination process, the surfactants were decomposed and eliminated completely, resulting in a clean surface of GNRs. Resultantly, these monolayer GNRs films explored as a SERS (surface-enhanced Raman spectroscopy) substrate have good uniformity and high sensibility for detecting probe molecules. Subsequently, the prepared SERS substrate was used to detect ultra-low concentration (10-9 mol·L-1) of pesticide molecules. |
