The reliability of two novel cortisol sensors was evaluated by detecting variations in salivary cortisol levels of college students. The diurnal salivary cortisol fluctuations in 50 college students were monitored, and the sensor results were compared with commercial immunoassays. The chemical sensors were prepared using two different methodologies; electrodeposition and cold atmospheric plasma deposition. The comparison between these two methods shows the potential of proposed methods over conventional cortisol assays. The sensitivity of plasma deposited cortisol sensor increased from 0.918 to 3.04 μ A/( μ g dl −1 ). Sensors fabricated using the plasma technique showed repeatability and provided a direct readout with a faster response.

交流—使用电沉积和等离子辅助沉积法检测氧化锌和卟啉铜复合材料对唾液皮质醇的检测

通过检测大学生唾液皮质醇水平的变化，评估了两种新型皮质醇传感器的可靠性。监测了50名大学生的唾液皮质醇的昼夜波动，并将传感器结果与商业免疫测定法进行了比较。化学传感器是使用两种不同的方法制备的；电沉积和冷大气等离子体沉积。两种方法之间的比较表明，与传统的皮质醇检测方法相比，该方法具有更大的潜力。血浆沉积皮质醇传感器的灵敏度从0.918提高到3.04μA /（μg dl -1）。使用等离子技术制造的传感器显示出可重复性，并提供了具有更快响应的直接读数。
