Abstract
A flexible glucose sensor is fabricated using O2 plasma-functionalized multiwalled carbon nanotube (MWCNT) films on polydimethylsiloxane (PDMS) substrates and its performance is electrochemically characterized. After enzyme immobilization, the GOD/ MWCNT/Au/PDMS electrode exhibits a sensitivity of 18.15 μA mm− 2mM− 1 and a detection limit of 0.01 mM (signal to noise ratio was about 3). This high sensitivity may be attributed to a large enzyme loading and a higher electrocatalytic activity and electron transfer exhibited by O2 plasma-functionalized CNTs than the pristine CNT, due to some oxygen-contained groups present on the O2 plasma-functionalized CNT surface, which has been verified by XPS spectrum.
