The identification of counterfeit drugs usually involves a variety of qualitative and quantitative methods such as chemical reactions, thin layer chromatography, liquid chromatography and hyphenated technology. However, these methods are time-consuming, require a large amount of samples, and are mostly destructive identification, so there are certain problems in their popularity.
With the development of chemometrics, spectroscopy has received widespread attention in the field of drug detection, especially Raman spectroscopy, which has become an important drug detection method due to its convenient and fast detection, small sample requirements, and no need for pretreatment. .
