A self-assembled electrochemical sensor for uranium

A self-assembled electrochemical sensor for uranium

Self-assembled ensembles of a disulphide derivative of para tertiary butyl calix arene 1,3 acid amide on polycrystalline gold have been shown to exhibit an electrochemical response proportional to the concentration of uranium in solution. This response is related to microscopic changes at the electr...

Zusammenfassung:Self-assembled ensembles of a disulphide derivative of para tertiary butyl calix arene 1,3 acid amide on polycrystalline gold have been shown to exhibit an electrochemical response proportional to the concentration of uranium in solution. This response is related to microscopic changes at the electrode surface induced by selective binding of uranium by the immobilised calixarene.
