摘要

在这项研究中,我们展示了一种方便的高性能便携式传感器平台,用于简单、快速、高效地检测H1N1病毒,该平台采用基于石墨烯的晶体管型架构。通过光刻和气相沉积等传统方法生成均匀的石墨烯层并进行图像化,随后在图像化的石墨烯层上引入电极以获得晶体管型传感器的几何形状。然后,用抗体对石墨烯表面进行功能化,用于H1N1病毒检测和传感器性能测试。测量传感器组分的过渡曲线、线性度和灵敏度(10 pfu/mL)。制作并演示了简易、快速、方便的便携式H1N1病毒检测平台。因此,与基于石墨烯的传感器组件相比,在便携式传感器平台上保持了传感器的性能。该便携式H1N1诊断平台的性能优于侧流法。

Graphene Field-Effect Transistor Based High-Performance Wireless Portable Device for H1N1 Detection
In this study, a convenient high-performance portable sensor platform for simple, fast, and efficient detection of H1N1 virus is demonstrated using a graphene-based transistor type architecture. A uniform graphene layer was generated and patterned by conventional methods such as lithography and vapor deposition, subsequently, electrodes were introduced on the patterned graphene layer to obtain transistor type sensor geometry. Then, the graphene surface was functionalized with antibody for H1N1 virus detection and sensor performance test. The transition curve, linearity, and sensitivity (10 pfu/mL) of the sensor component were measured. In addition, the portable H1N1 diagnosis platform for simple, fast, and convenient virus detection was produced and demonstrated. Consequently, the sensor performance was maintained in the portable sensor platform compared with the graphene-based sensor component. This presented portable H1N1 diagnosis platform showed better performance than the lateral flow assay.
