In order to achieve rapid, non‐destructive, efficient, and accurate classification of paper cup samples, we propose a classification model that integrates shifted‐excitation Raman difference spectroscopy (SERDS) with self‐organizing map (SOM) and Bayesian optimization–support vector machine (BO‐SVM). We collected differential Raman data from 52 paper cup samples using SERDS, with an excitation wavelength...
Rapid drug detection is vital for combating drug abuse and inhibiting transmission, and the emergence of various novel psychoactive substances (NPS) has placed higher demands on field testing. To establish a rapid, nondestructive, and accurate analytical and classification method for testing novel psychoactive substances, shifted‐excitation Raman difference spectroscopy (SERDS) was used to detect...
