Three-dimensional nitrogen-doped graphene (3D N-doped graphene) was prepared through chemical vapor deposition (CVD) by using porous nickel foam as a substrate. As a model, a dopamine biosensor was constructed based on the 3D N-doped graphene porous foam. Electrochemical experiments exhibited that this biosensor had a remarkable detection ability with a wide linear detection range from 3 × 10(-6) M to 1 × 10(-4) M and a low detection limit of 1 nM. Moreover, the fabricated biosensor also showed an excellent anti-interference ability, reproducibility, and stability.
通过化学气相沉积（CVD）法，以泡沫镍为基底制备了三维氮掺杂石墨烯（3D N掺杂石墨烯）。作为一个模型，基于3D N掺杂石墨烯多孔泡沫构建了多巴胺生物传感器。电化学实验表明，该生物传感器具有显著的检测能力，线性检测范围宽，为3×10（-6）M至1×10（-4）M，检测限低至1 nM。此外，所制备的生物传感器还表现出优异的抗干扰能力、重现性和稳定性。
