| 题目: | Simultaneous Capture, Detection, and Inactivation of Bacteria as Enabled by a Surface-Enhanced Raman Scattering Multifunctional Chip** | | | | | 作者: | [*] Dr. H. Wang,[+] Dr. Y. Zhou,[+] X.

The developed SERS chip is made of a silicon wafer decorated with silver nanoparticles and modified with 4-mercaptophenylboronic acid (4-MPBA). It was prepared in a straightforward manner by chemical reduction assisted by hydrogen fluoride etching, followed by the conjugation of 4-MPBA through Ag[1]S bonds. The dominant merits of the fabricated SERS chip include excellent reproducibility with a relative standard deviation (RSD) value smaller than 11.0%, adaptable bacterial-capture efficiency (ca. 60%) at low concentrations (500�2000 CFUmL[1]1), a low detection limit (down to a concentration of 1.0 [1] 102 cellsmL[1]1), and high antibacterial activity (an antibacterial rate of ca. 97%). The SERS chip enabled sensitive and specific discrimination of Escherichia coli and Staphylococcus aureus from human blood. | | | | | 影响因子: | 11.336 | | | | | 分区情况: | 1区 | | | | | 链接: | http://onlinelibrary.wiley.com/doi/10.1002/anie.201502752/abstract |
