Machine learning-driven grating-like SERS Platform toward ultra-sensitive detection of forsythin

High-performance grating-like SERS substrate based on machine learning for ultrasensitive detection of Zexie-Baizhu decoction

“…In addition, we quantified the intensities of 1141 cm −1 and 1439 cm −1 peaks at these 6 positions to determine the relative standard deviation (RSD). The formula below was employed to compute the RSD [ 52 ]: where n denotes the quantity of Raman spectra, is the Raman signal intensity, and represents the average Raman signal intensity. In Fig.…”
