Fabrication of Peptide immobilized Plasmonic Sensor for Detection of Bifenthrin |
| 초록 |
In 2017, egg contamination scandal was occurred by pesticides in Europe and South Korea. One of the main reasons was bifenthrin. Bifenthrin is a pyrethroid pesticide, widely used for agriculture. United States Environmental Protection Agency (US EPA) classified bifenthrin as a Category C, which means possible human carcinogen. We demonstrated a biosensor for selective detection of bifenthrin in samples. Briefly, this is a plasmonic sensor applying the self-assembly of the gold nanoparticles, was used to conduct density deposition on a transparent glass substrate in order to achieve a regulated diameter of gold nano particle monolayer, which produced longitudinal wavelength extinction shifts through the localized surface plasmon resonance (LSPR) signal. The developed peptides conjugated the LSPR sensing chips are selected with phage display technique. We also use enzyme-linked immunosorbent assay (ELISA) to figure out the binding affinity of peptide attach to bifenthrin. |
