For its powerful antimicrobial properties, nanosilver is the most widely used nanoparticle in commercial odor-neutralizing and anti-infective textiles. However, the recent prevalent use of nanosilver has prompted concerns for the potential adverse human and environmental effects caused from the leaching of nanosilver during usage and laundering, necessitating innovative strategies in characterizing nanosilver on textile substrates. This study investigated the viability of surface-enhanced Raman spectroscopy (SERS) as an analytical method for the characterization and quantification of nanosilver (silver nanoparticles, 12.4 ± 5.1 nm) in cotton. Two indicators, iron (III) tris (dimethyldithiocarbamate) (ferbam) and rhodamine 6G (R6G) were used to compare how efficiently they bind onto nanosilver incorporated into cotton (nanosilver-cotton) and exhibit signature SERS responses. Comparing the SERS spectra of the two indicators, R6G was found to be more appropriate for nanosilver-cotton. The solvent system for R6G was important in enhancing the SERS intensity in the cotton medium – the intensity obtained from water was nearly threefold greater than those from methanol and the 50:50 mixture of water and methanol. A linear correlation (R² = 0.9761) between the intensity at 1503 cm⁻¹ of R6G and the concentration of nanosilver in cotton was developed and was validated by analyzing the washing stability of nanosilver-cotton fabrics through simulated laundering cycles. The technique was also successfully applied to spatially resolve the distribution and aggregation of nanosilver on textile fabrics by mapping a coffee-ring deposition produced by the surface application of nanosilver to textile samples of raw cotton, scoured raw cotton, and 50:50 and 80:20 blends of polyester-cotton. These results validate SERS as a rapid and facile tool for monitoring the dispersion and concentration of nanosilver on textiles after application and laundering.

纳米银因其强大的抗菌性能而成为在商业气味中和和抗感染纺织品中使用最广泛的纳米颗粒。但是，近来纳米银的普遍使用引起了人们对在使用和洗涤过程中浸出纳米银可能造成的潜在的不利人类和环境影响的关注，这需要在纺织品基材上表征纳米银的创新策略。这项研究调查了表面增强拉曼光谱（SERS）的可行性，作为表征和定量分析棉花中纳米银（银纳米粒子，12.4±5.1 nm）的一种分析方法。两个指标 使用三（二甲基二硫代氨基甲酸酯）铁（ferbam）和罗丹明6G（R6G）来比较它们与结合到棉中的纳米银（纳米银棉）结合的效率，并表现出标志性的SERS反应。比较这两个指标的SERS光谱，发现R6G更适合纳米银棉。R6G的溶剂体系对于提高棉介质中的SERS强度非常重要-从水中获得的强度几乎是从甲醇以及水和甲醇的50:50混合物中获得的强度的三倍。线性相关（R R6G的溶剂体系对于提高棉介质中的SERS强度非常重要-从水中获得的强度几乎是从甲醇以及水和甲醇的50:50混合物中获得的强度的三倍。线性相关（R R6G的溶剂体系对于提高棉介质中的SERS强度非常重要-从水中获得的强度几乎是从甲醇以及水和甲醇的50:50混合物中获得的强度的三倍。线性相关（R研究了R6G 在1503 cm ^-1处的强度与棉中纳米银浓度之间的关系，得出² = 0.9761），并通过模拟洗涤周期分析纳米银棉织物的洗涤稳定性，从而验证了该有效性。该技术还通过将纳米银表面施涂到原棉，精练原棉以及50:50和80:50的纺织品样品上的咖啡环沉积图绘制而成，成功地将这种技术用于空间分辨纺织品上纳米银的分布和聚集。 20涤棉混纺。这些结果证明，SERS是一种快速，简便的工具，可在施用和洗涤后监测纳米银在纺织品上的分散度和浓度。
