【摘要】 柔性传感器在可穿戴微型智能设备的开发中具有重要的意义。本研究报告了一种基于还原氧化石墨烯（rGO）的柔性电化学平台,用于水杨酸（SA）的检测。采用简单的挤压工艺制备了独立的柔性还原氧化石墨烯电极。动态机械变形和弯曲研究表明了该柔性电极具有较强的柔韧性和可弯曲能力。以该柔性rGO电极为工作电极,采用差分脉冲伏安法（DPV）对SA进行了定量分析。SA的线性范围为1.0×10^-10 M～1.0×10^-5 M,检出限为2.3×10^-11 M （S/N=3）。这一策略为柔性电极的设计和应用开创了新的视觉,有利于rGO在传感器、生物电子和芯片医疗设备中更好地应用。更多还原

【Abstract】 Flexible sensors are of considerable interest for the development of wearable smart miniature devices.This work reported a flexible electrochemical platform based on reduced graphene oxide（rGO） for the detection of salicylic acid（SA）.The free-standing and flexible rGO electrode was prepared via a simple extruded process.Dynamic mechanical deformation and bending studies illustrated the resilience and compliance of the flexible electrode against extreme mechanical deformations.Quantitative analysis of SA was performed by using differential pulse voltammetry（DPV） with this flexible rGO electrode.Linearity ranges for SA were obtained from1.0×10^-10 M to 1.0×10^-5 M with the detection limit of 2.3×10^-11 M（S/N=3）.This strategy provided a new insight into the design and application of flexible electrodes.It will extend the applications of r GO in sensing,bio-electronics and lab-on-chip devices.更多还原
