本研究旨在开发一种新型低成本智能手机生物传感器系统,建立唾液α-淀粉酶(sAA)这一潜在压力生物标志物的高效检测方法。该系统由带sAA检测应用的智能手机、丝网印刷电极(SPEs)和恒电位仪模块组成。所提技术通过施加微小扰动获得线性化响应,可避免循环伏安法反复氧化还原样品而改变样品组成。应用研究中,6名健康研究生接受5分钟特里社会压力...

本研究旨在比较三种方法测定唾液α-淀粉酶(sAA)水平并分析影响因素。38名健康志愿者提供唾液样本:先将采集条置于舌下2分钟,立即用手持生物传感器现场测定(口内法);随后被动聚集唾液4分钟并收集至管中,分装后分别用手持生物传感器(口外法)和标准酶动力学法(EKA)测定。另设实验比较不同唾液聚集时间和采集条位置对结果的影响。结果显示,...
