A simple approach for simultaneous detection of cadmium(II) and lead(II) based on glutathione coated magnetic nanoparticles as a highly selective electrochemical probe

Baghayeri, Mehdi ; Amiri, Amirhassan ; Maleki, Behrooz ; Alizadeh, Zahra ; Reiser, Oliver


We introduce the synthesis and electrochemical application of a glutathione functionalized magnetic nano composite (GSH@Fe3O4) for the development of a simple, stable and selective sensor for heavy metal ion detection in real-life samples for the first time. The monitoring method is based on electrochemical pre-concentration/reduction of metal ions onto a GSH@Fe3O4 modified magnetic glassy carbon ...
