Purpose

A bio-sensor has been developed in this study for the purpose of point-of-care diagnostics. Point-of-care-diagnostic is a type of diagnosis where the diagnostic centre, i.e. the diagnosis kit is made available at the location of the patient when the patient needs immediate action. In this process of diagnosis a compact, portable, integrated kit must be available which can diagnose the disease of the patient by testing various analytes.

Design/methodology/approach

Using a fully experimental methodology, a blood glucose sensor is made by conducting carbon interdigitated electrode (IDE) on a flexible substrate. IDEs are used to increase the effective capacitance of the structure, as well as the effective electroactive area of the sensor. Interdigitated structure permits two-electrode sticks with “each other” and “infuse” together. As a consequence, the distance between electrodes can be tuned to a much smaller value than traditional thin-film architectures. Narrowing the distance between electrodes allows for fast ion diffusion that offers better rate capability and efficiency in power density. The fabricated device exhibits a remarkable value of sensitivity in the order of 2.741 µA mM-1 cm⁻².

Findings

A highly sensitive, portable and inexpensive blood glucose sensor has been developed in this context.

Originality/value

This research study can be a scope for future research in the field of bio-sensors.

用于血糖传感的柱状指间电极的制备与表征

目的

为了进行即时诊断，本研究开发了一种生物传感器。即时诊断是一种诊断类型，其中当患者需要立即采取行动时，可以在患者所在地使用诊断中心，即诊断工具包。在此诊断过程中，必须提供紧凑，便携式，集成的套件，该套件可以通过测试各种分析物来诊断患者的疾病。

设计/方法/方法

使用完全实验性的方法，通过在柔性基板上导通碳指叉电极（IDE）制成血糖传感器。IDE用于增加结构的有效电容以及传感器的有效电活性区域。叉指结构允许两电极棒彼此“互相”和“注入”在一起。结果，电极之间的距离可以调整到比传统的薄膜架构小得多的值。缩小电极之间的距离可实现快速的离子扩散，从而提供更好的速率能力和功率密度效率。所制造的器件表现出显着的灵敏度值，约为2.741 µA mM-1 cm ^-2。

发现

在这种情况下，已经开发出了高度灵敏，便携式且廉价的血糖传感器。

创意/价值

这项研究可以作为生物传感器领域未来研究的范围。
