Fig. 1From: Electroanalytical biosensor based on GOx/FCA/PEG-modified SWCNT electrode for determination of glucoseSchematic diagram of a the fabrication of SWCNT electrodes by O2-plasma treatment and b the construction of glucose biosensors based on a three SWCNT electrode system. The gap between the PET substrate and hydrophilic cover film produced by Teflon tape allows the capillary addition of a sample with a volume less than 10 μL.
