摘要

深共晶溶剂（DES）近来已成为纳米粒子合成的替代溶剂。在银纳米粒子（Ag NPs）的制备方面已经取得了许多进展，但人们既没有考虑也没有仔细研究 DESs 在银纳米粒子合成中的潜力。在本研究中，我们提出了一种在 DES（Ag NPs-DES）中制备 Ag NPs 的新策略。由ᴅ-葡萄糖、尿素和甘油组成的 DES 不含任何阴离子，不会与 Ag+ 阳离子发生沉淀。我们的 Ag NPs-DES 样品被用于表面增强拉曼散射（SERS）传感器。用于 SERS 定量的两种分析物是硝基呋喃妥因（NFT）和磺胺嘧啶（SDZ），其残留量可低至 10-8 M。此外，在 10-8 到 10-3 M 的浓度范围内，线性系数都非常接近 1，SERS 底物显示出显著的均匀性和极高的选择性。这种强大的 SERS 性能表明 DESs 在合成用于构建生物传感器基底的纳米材料方面具有巨大的潜力。

Potential of a deep eutectic solvent in silver nanoparticle fabrication for antibiotic residue detection

Deep eutectic solvents (DESs) have recently emerged as an alternative solvent for nanoparticle synthesis. There have been numerous advancements in the fabrication of silver nanoparticles (Ag NPs), but the potential of DESs in Ag NP synthesis was neither considered nor studied carefully. In this study, we present a novel strategy to fabricate Ag NPs in a DES (Ag NPs-DES). The DES composed of ᴅ-glucose, urea, and glycerol does not contain any anions to precipitate with Ag+ cations. Our Ag NPs-DES sample is used in a surface-enhanced Raman scattering (SERS) sensor. The two analytes for SERS quantitation are nitrofurantoin (NFT) and sulfadiazine (SDZ) whose residues can be traced down to 10−8 M. The highest enhancement factors (EFs) are competitive at 6.29 × 107 and 1.69 × 107 for NFT and SDZ, respectively. Besides, the linearity coefficients are extremely close to 1 in the range of 10−8 to 10−3 M of concentration, and the SERS substrate shows remarkable uniformity along with great selectivity. This powerful SERS performance indicates that DESs have tremendous potential in the synthesis of nanomaterials for biosensor substrate construction.
