Amplification strategy based on gold nanoparticle-decorated carbon nanotubes for neomycin immunosensors.


A novel amperometric immunosensor with an enhanced sensitivity for the detection of neomycin (Neo) was prepared by covalently immobilizing a monoclonal Neo antibody onto a new conducting polymer, poly-[2,5-di-(2-thienyl)-1H-pyrrole-1-(p-benzoic acid)] (pDPB), as a sensor probe. The probe was used to detect Neo in a sandwich-type approach, where the… (More)
