With the increasing public concern on food quality, the qualitative and quantitative analysis of trace banned substances in food is prospering in the field of food safety. A rapid and sensitive detection strategy for trace antibiotics in livestock was developed using surface-enhanced Raman spectroscopy. The proposed SERS-based strategy showed accurate qualification and reliable quantitation compared to standard HPLC-MS/MS technique, providing a practical method for rapid detection of other similar substances in real samples.
With the increasing public concern on food quality, especially the zero-tolerance of illegal additives, the rapid qualitative and quantitative analysis of trace banned substances in food is in a prosperity stage in the field of food safety. Here, by combining with a self-developed rapid pretreatment kit, an on-site, rapid and sensitive detection strategy for trace antibiotics such as enrofloxacin and ciprofloxacin, two typical abused antibiotics in livestock and other industries, by surface-enhanced Raman spectroscopy (SERS) technique was developed. The abused quinolones residues in chicken meat (3 kinds of silky chicken meat and 2 kinds of plain chicken meat) were successfully screened by the developed SERS method, which showed an accurate qualification and a reliable quantitation in comparison with that by standard high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) technique. The proposed SERS-based strategy may provide a practical and simple method for rapid detection of other quinolones in real samples.
