NOVELTY - Use of an ordered vertical porous graphene is claimed for preparing blood sugar test paper and as a working electrode. The glucose dehydrogenase enzyme solution is fixed on graphene wall after spraying enzyme solution on working electrode. USE - Ordered vertical porous graphene for preparing blood sugar test paper and as a working electrode. ADVANTAGE - The ordered vertical porous graphene has good fixing effect on graphene wall, short diffusion distance of conductive medium, fast reaction speed, increases sensitivity of electrode to grape reaction, effectively expands test range of blood glucose test paper, which is good for transmitting test current, increases current discrimination, improves precision value of low and high concentration blood sample, test concentration range is 0.5-35mmol/L, precision is controlled in 2.5%, detection time is 5 seconds, and blood intake is 1.0 mu L.
