Internal standard optimization advances sensitivity and robustness of ratiometric detection method

Analyst, 2024, Advance Article DOI: 10.1039/D4AN00266K, CommunicationYuning Jiang, Jiaying Cao, Sen Hu, Tao Cheng, Hanyu Wang, Xiaoyu Guo, Ye Ying, Xinling Liu, Feng Wang, Ying Wen, Yiping Wu, Haifeng Yang We detect nitrite with pATP/Au/ITO chipvia ratiometric SERS method. With the 1008 cm−1 SERS peak from ring deformation as the internal standard (replacing the traditional 1080 cm−1 C-S stretching peak), the detection sensitivity is 10-fold increase.
