| 제목 | Label-Free SERS Selective Detection of β-Lactamases Using Solid Phase Microextraction |
| 초록 | β-lactamase is an important bacterial enzyme with the ability to efficiently cleave β-lactam antibiotics. Therefore, there are reports of unscrupulous manufacturers illegally adding β-lactamase into milk to hide antibiotic residues. It is important to develop a reliable and highly sensitive on-site and real-time detection of β-lactamase in dairy products. Surface-enhanced Raman spectroscopy (SERS) is a highly sensitive, fingerprint-based, fast analysis technique. We combined solid phase microextraction (SPME) and SERS technique to develop a rapid and highly sensitive detection method for β-lactamase in dairy products. In this work, Ag-loaded TiO2 nanotube arrays fiber exhibited remarkable SERS activity and SPME selectivity. The results were shown that β-lactamase in milk solution at a low concentration of 0.5U/L can be easily detected without any pretreatment. |
