Application of 4-mercaptophenyl Boronic Acid-incorporated Ag embedded Silica-coated Graphene Oxide for Detection of Glucose |
| 초록 |
In this work, 4-mercaptophenyl boronic acid (4-MPBA) was prepared for detect glucose by surface enhanced Raman scattering (SERS) on the surface of silver nanoparticle-embedded silica-coated graphene oxide (GO@SiO2@Ag NPs@MPBA). The SERS intensity of 4-MPBA on the GO@SiO2@Ag NPs was 2.2 times stronger than GO@Ag NPs. Also, silica-coated GO showed a low background signals comparing GO. The SERS intensity of GO@ SiO2@Ag NPs@MPBA peaked at 1 mM 4-MPBA. Then, pH-dependent behavior of 4-MPBA on the GO@SiO2 @Ag NPs was investigated. The highest SERS signal intensity was indicated at pH 3. The 4-MPBA-incorporated GO@SiO2@Ag NPs which were united to glucose increased the SERS signals at both 1,072 and 1,588 cm-1. The range of glucose was estimated from 2 to 20 mM . These results provide a lot of application into detection of glucose and progress the SERS-based biosensors using graphene oxide as a substrate. |
