Fig. 5From: Electroanalytical biosensor based on GOx/FCA/PEG-modified SWCNT electrode for determination of glucosea Chronoamperometry responses of glucose biosensor after the addition of a glucose solution with a concentration range of 0–40 mM. All responses were obtained at a constant cell potential of 0.3 V. b Calibration plot for a glucose biosensor. Inset: corresponding Lineweaver–Burk plotBack to article page
