A highly sensitive and reproducible lead sensor based on a cyclodextrin-modified gold electrode was created. A self-assembled monolayer (SAM) of thiolated β-cyclodextrin (6-(2-mercapto-ethylamino)-6-deoxy-β-cyclodextrin (MEA-β-CD)) was prepared and modified on a gold electrode (MCGE) for specific Pb 2+ -sensing. Thus the mercury-free sensors for Pb 2+ assay based on MCGE were established...
Phenylephrine (i.e. PHE) and chlorprothixene (i.e. CPT), two effective and important antipsychotic drugs with low redox activity, were found generating an irreversible anodic peak at about +0.89V (vs. SCE) and +1.04V in 0.05M HAc–NaAc (pH 5.0) or NH 2 CH 2 COOH–HCl (pH 2.4) buffer solution at poly(4-aminobenzene sulfonic acid) modified glassy carbon electrode (i.e. poly(4-ABSA)/GC),...
A poly-ABSA/SWNTs composite-modified electrode was fabricated by electropolymerizing aminobenzene sulphonic acid (ABSA) on the surface of glassy carbon electrode (GCE) modified with single-wall carbon nanotubes (SWNTs). SWNTs provide a 3D porous and conductive network for the polymer immobilization. The nanocomposite film was characterized by scanning electron microscope (SEM) and electrochemical...
