Electrochemical detection of paracetamol at multi wall carbon nanotubes/titanium dioxide composite modified electrode.

Electrochemical behaviour of paracetamol at the multi wall carbon nanotubes/titanium dioxide (MWCNT/TiO2) composite film modified glassy carbon electrode (GCE) via solvent casting method was studied. It is shown that the MWCNT/TiO2/GCE exhibits remarkable improvement in analytical response as compar...
