Abstract

The accurate detection of antibiotic residues in the environmental and food samples is crucial for ensuring ecosystem safety and human health. Surface enhanced Raman spectroscopy (SERS) has emerged as a powerful analytical technique due to its specificity and sensitivity. In this study, we present the synthesis of noble-metal/2D-semiconductor composites consisting of silver nanospheres and bismuth oxybromide microflowers (Ag-NSs/BiOBr-MFs) for SERS antibiotic detection of nitrofurantoin (NFT). The characteristics of Ag-NSs/BiOBr-MFs composite was examined using various microscopic and spectroscopic methods. The Ag-NSs/BiOBr-MFs composite exhibits precise quantitative detection of NFT in the concentration range from 10–4 to 10–12 M with a good linear relationship. The NFT detection using the Ag-NSs/BiOBr-MFs composite demonstrates superior SERS performance, including an ultralow limit of detection of 1.86 × 10–12 M and a high enhancement factor of 2.75 × 1010. The highly effective SERS performance of Ag-NSs/BiOBr-MFs composite is due to the formation of numerous hot spots, the effective charge transfer across wide heterogeneous interface, and the synergistic action of electromagnetic and charge transfer mechanisms. The Ag-NSs/BiOBr-based SERS substrate successfully detects the NFT spiked in actual samples with interference compounds, achieving an ultra-low limit of detection of 3.55 × 10–12 M. These findings highlight the attractive performance of the Ag-NSs/BiOBr-MFs composite-based SERS platform, which holds great potential for practical applications in sensitive food and environmental detection.

释放氧化溴化铋微花支撑银纳米球作为呋喃托因检测的SERS平台的潜力
准确检测环境和食品样品中的抗生素残留对确保生态系统安全和人类健康至关重要。由于其特异性和敏感性,表面增强拉曼光谱(SERS)已成为一种强大的分析技术。在这项研究中,我们合成了由银纳米球和氧化溴化铋微花组成的贵金属/ 2d半导体复合材料(Ag-NSs/BiOBr-MFs),用于呋喃托因(NFT)的SERS抗生素检测。采用各种显微和光谱学方法研究了Ag-NSs/BiOBr-MFs复合材料的特性。Ag-NSs/BiOBr-MFs复合材料在10-4 ~ 10-12 M的浓度范围内具有良好的线性关系,可以精确定量检测NFT。Ag-NSs/BiOBr-MFs复合材料的NFT检测显示出优越的SERS性能,包括1.86 × 10-12 M的超低检测限和2.75 × 1010的高增强因子。Ag-NSs/BiOBr-MFs复合材料之所以具有高效的SERS性能,是由于其形成了众多的热点,在宽的非均质界面上进行了有效的电荷转移,以及电磁和电荷转移机制的协同作用。Ag-NSs/ biobr基SERS底物成功地检测了含有干扰化合物的实际样品中的NFT,达到了3.55 × 10-12 m的超低检测限。这些发现突出了Ag-NSs/BiOBr-MFs复合SERS平台的诱人性能,在敏感食品和环境检测中具有巨大的实际应用潜力。
