Homogeneous dispersion of graphene nanosheets in water by hybridization with conjugated polymer |
| 초록 |
Graphene nanosheets hybridized with conjugated polymer (PDA, polydiacetylene) were prepared for homogeneous dispersion and further functionality of graphene in water. Diacetylenic monomers were self-assembled and photo-polymerized on reduced graphene oxide (RGO) for non-covalent functionalization. The PDA/RGO nanohybrids demonstrated the formation of conjugated polymer on graphene surface for fluorescence and electrochemical detection. The optical and structural properties of PDA/RGO nanohybrids, characterized by UV-Vis, FT-IR, Raman, and photoluminescence spectrometers, supported that PDA and RGO are connected by physical interactions and not by chemical bonds. Further-functionalization of PDA/RGO with biotin was verified in microfluidic biochip via biotin-straptavidin interaction. The electrochemical experiments showed the potential of functionalized RGO for use as an electrochemical biosensor, especially with the detection of an analyte at low concentration. |
