Since Raman effect appeared in 1928, Raman spectroscopy has become an important means to detect and analyze material structure. Raman spectroscopy is a spectroscopic technique that detects molecular vibrations to characterize the underlying chemical structure of a sample.
With the development of the social economy, people eat more and more abundant foods, and their ingredients and varieties have great differences. Nowadays, people pay more and more attention to food safety. In the process of food safety inspection, Raman spectroscopy technology can detect pesticides and oil content in food, but it still requires in-depth research by technicians to improve the effectiveness of Raman spectroscopy technology in food inspection.
A portable Raman spectrometer was developed according to the features of fabricated SERS ding to the features of fabricated SERS chips. With the Raman signal enhancement of graphene SERS chips, the Raman spectrometer can realize the detection of trace substances with low cost and fast speed, which is a powerful tool and fast speed, which is a powerful tool for food testing, disease diagnosis and environment monitoring.
With the rapid development of industrial activities, the green and environmentally friendly methods for the treatment of metal pollution and the recycling of resources have received extensive interest. Thermosensitive ion-imprinted material which has the advantages of sensitivity and ion-imprinting technology is potential in processing heavy metal pollution and exploitation of rare metal resources.
