This study explores the theoretical foundation behind the application of surface-enhanced Raman spectroscopy (SERS) for neonicotinoid quantification. Our findings demonstrate that SERS intensities are determined by the thermodynamic adsorption behaviors of neonicotinoid molecules transitioning from aqueous phases to gold nanoparticle (AuNP) surfaces. The dynamic ranges and limits of detection can be accurately predicted by classic adsorption isotherms.

新兴研究者系列：对水中新烟碱类杀虫剂浓度和 SERS 强度之间关系的定量见解


本研究探讨了应用表面增强拉曼光谱（SERS）进行新烟碱类杀虫剂定量的理论基础。我们的研究结果表明，SERS 强度是由新烟碱类分子从水相过渡到金纳米颗粒 (AuNP) 表面的热力学吸附行为决定的。动态范围和检测限可以通过经典吸附等温线准确预测。
