Embodiment 1
[0035] A method for preparing an enzyme-free biosensor based on nitrogen-doped graphene in this embodiment, the specific preparation steps are as follows:
[0036] (1) The glassy carbon electrode with a diameter of 3 mm is sequentially filled with Al with a diameter of 0.3 μm and 0.05 μm 2 o 3 The powder was polished into a mirror surface, rinsed with distilled water, and then ultrasonically cleaned in absolute ethanol and distilled water for 1 min, and then the treated glassy carbon electrode was placed in 0.5mol / L H 2 SO 4 In the solution, the electrochemical redox is carried out at the potential window of -0.3-1.5V, the glassy carbon electrode is activated and the residue on the electrode surface is removed.
[0037] (2) Take 100mg of graphite oxide in a beaker, add 50mL of deionized water and ultrasonically strip it for 4h, then add 6.25mL of FeCl3 ·6H 2 O solution and 235 μL of pyrrole monomer were placed in the reactor at 40°C for 1 hour and stirred at a constant temp...
