| Abstract: | A novel molecular imprinted(MIP) film/Au nanoparticles(AuNP) modified glassy carbon electrode(GCE),L-Cys/AuNP/GCE(MIP),was prepared by electrochemical deposition of gold nanoparticles and electrochemical assembly of L-Cys at the surface of GCE using bromophos ethyl as template molecular.The results indicate that L-Cys/AuNP/GCE(MIP) can selectively recognize bromophos ethyl and be applied for the electrochemical determination of bromophos ethyl in the spiked sample.Under the optimized conditions,the electroc... |
