Abstract

The biotin biomolecule has been sensed with the help of designed MEMS sensor. It takes advantage of MEMS technology where ZnO-WO3 mixed nanomaterial is used with cavity structure as a capacitive biosensor for higher sensitivity. The freshness of foods where biotin is mostly present (> 10ug/100g) can be easily detected using the proposed structure. The proposed structure is analyzed using Intellisuit-7 simulator and further it is fabricated using sol-gel method and cavity design techniques. When the sensor is placed inside the food the overall sensor capacitance changes with time as the food quality gets deteriorated. The reason is change of dielectric (Єk) value. Due to homogeneous structure of the biosensor it produces linear response in terms of change of dielectric with time. Further, SEM and XRD processes are used to analyze the distribution of molecules at micro scale level. Significant capacitance shifts is observed for change of time span of 12 days due to biotin’s dielectric change which directly shows quality standard of food.
用于食品质量检测的ZnO-WO3混合金属薄膜电容式生物传感器
利用所设计的MEMS传感器对生物素分子进行了传感。利用MEMS技术,将ZnO-WO3混合纳米材料与空腔结构结合,作为电容式生物传感器,具有更高的灵敏度。使用所提出的结构,可以很容易地检测出生物素主要存在的食物的新鲜度(bb0 - 10ug/100g)。采用Intellisuit-7仿真器对所提出的结构进行了分析,并采用溶胶-凝胶法和空腔设计技术对所提出的结构进行了制备。当传感器放置在食品内部时,随着食品质量的恶化,传感器的整体电容随时间而变化。原因是介电(Єk)值的变化。由于生物传感器结构均匀,其电介质随时间的变化呈线性响应。利用扫描电镜(SEM)和x射线衍射(XRD)分析了分子在微观尺度上的分布。生物素介电常数的变化在12天的时间跨度内观察到明显的电容变化,这直接反映了食品的质量标准。
