Glucose Detection as a SERS Substrate that Used with 4-mercaptophenyl Boronic Acid-embraced Silver Nanoparticles-embedded Silica-coated Graphene Oxide |
| 초록 |
In this paper, to detect glucose by surface enhanced Raman scattering (SERS), 4 -mercaptophenyl boronic acid (4-MPBA) was self-assembled 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-fold greater than that of GO@Ag NPs. Furthermore, silica-coated GO exhibited lower background signals compared to GO. The SERS intensity of GO@SiO2@Ag NPs@MPBA peaked at 1 mM 4-MPBA. pH- dependent tendency of 4-MPBA on the GO@SiO2@Ag NPs was investigated; the highest SERS signal intensity was detected at pH 3. The binding of glucose to 4-MPBA-incorporated GO@SiO2@Ag NPs increased the SERS signals at both 1,072 and 1,588 cm-1. The linear range was recorded from 2 to 20 mM glucose. These results provide insight into detection of glucose and the development of SERS-based biosensors using graphene oxide. |
