Abstract

Multiwalled carbon nanotubes (MWCNT) have been used for modification of working graphite ink electrode of the three‐electrode screen‐printed sensing stripe. Modification has been made by evaporating on the graphite surface a solution of MWCNT in dimethylformamide. The effect of modification on reversibility of the electrode process of the system hexacyanoferrate(II)/(III) has been shown, along with improvement of the sensitivity of detection of pesticide paraoxon with biosensors containing organophosphorus hydrolase immobilized by adsorption on the nanotubes‐modified graphite ink electrode. The catalytic sensing of methanol was also demonstrated with the use of a screen‐printed sensor modified with MWCNT and Co(II) salt present in the measuring solution.
