Abstract
Chemically modified electrodes have been widely used to enhance electrochemical monitoring ofanalytes that are not easily detected using traditional base conductive materials. We have investigateddifferent fabrication approaches to chemically modify multi-wall carbon nanotube (MWCNT) compositeelectrodes with Prussian blue (PB). Composite electrodes were made where Prussian blue was mixedwith MWNCTs, where Prussian blue was coated on MWCNT composite electrodes and where MWCNTswere modified by generating PB on the surface of MWCNTs. Ourfindings indicate that MWCNT modifiedPB electrodes provided good sensitivity for the detection of glutathione and exceptional stability; whilstMWCNT coated PB electrodes provided excellent sensitivity but poor stability. Suchfindings provideimportant implications on the fabrication, suitability and use of chemically modified electrodes forelectroanalysis.
