Fabrication of gold nanoparticle-dihexadecyl hydrogen phosphate film on a glassy carbon electrode, and its application to glucose sensing

A gold nanoparticles-dihexadecyl hydrogen phosphate (DHP) film on a glassy carbon electrode (GCE) was fabricated. Gold nanoparticles were dispersed into DHP solution to give a homogeneous and stable suspension. A stable and uniform Au-nano-DHP film was obtained on the GCE surface using a convenient coating technique. This nanostructured electrode exhibited excellent sensing for the oxidation of glucose. A novel electroanalytical method for the determination of glucose was developed.
