Novel flexible bifunctional amperometric biosensor based on laser engraved porous graphene array electrodes: Highly sensitive electrochemical determination of hydrogen peroxide and glucose.

聚酰亚胺-激光雕刻多孔石墨烯（LEPG）因制备高效、成本低，是柔性电化学传感的有前途电极修饰材料。本文通过简单新颖的直接激光雕刻制备柔性、多图案、微型化电极。具有多孔网络结构的三维 LEPG 可经原位电化学沉积选择性修饰铂纳米粒子（Pt NPs），形成 Pt-LEPG，用作高灵敏 H2O2 传感器，具有宽线性范围（0.01–29 n...
