A disposable organophosphorus pesticides (OPs) enzyme biosensor based on magnetic composite nanoparticle-modified screen printed carbon electrodes (SPCE) has been developed. Firstly, an acetylcholinesterase (AChE)-coated Fe(3)O(4)/Au (GMP) magnetic nanoparticulate (GMP-AChE) was synthesized. Then, GMP-AChE was absorbed on the surface of a SPCE modified by(More)
A novel amperometric immunoassay for identification of Escherichia coli (E.coli) in a matrix containing zirconium dioxide nanoparticles (ZrO<inf>2</inf>) was described. Firstly, the antibody of E.coli (anti E.coli) was immobilized on a glassy carbon electrode (GCE) modified with carbon nanotubes (CNTs) using ZrO<inf>2</inf> nanoparticles, colloidal gold(More)
