Virus-decorated AgNWs as a Surface-enhanced Raman Scattering (SERS) Biosensor for Selective Pesticide Detection |
| 초록 |
A surface-enhanced Raman scattering (SERS) sensor comprised of silver nanowires (AgNWs) and genetically modified M13 Bacteriophages (BPWHW) was fabricated onto a glass-fiber filter paper (GFFP). AgNWs stacked on GFFP formed SERS-active hot-spots and the decorated BPWHW functioned as receptor for selective pesticide detection. The SERS effect and the selective pesticide detection capability were analyzed compared with wild-type M13 bacteriophage-decorated AgNWs (BPWT/AgNW) and undecorated AgNWs (AgNW). The developed BPWHW/AgNW selectively identified paraquat (PQ) molecule rather than other bipyridylium pesticides such as diquat (DQ) and difenzoquat (DIF). Field application test on PQ pre-treated apple peels demonstrated the feasibility of using paper-based SERS substrate for on-site residual pesticide detection. The developed SERS sensor is expected to be applied for various pesticides and chemicals detection through modification of the M13 bacteriophage surface peptide sequences. |
