Research output: Contribution to journalConference article


We propose a newly developed stress analysis system combined with quartz crystal microbalance (QCM) method and a self-suction flow system. Cortisol, well known as a stress marker, was targeted in this study. The proposed system can be performed as quantitative analysis without professional skills by only dropping a liquid sample with the addition ofatracer. The system could detect Cortisol within 8 minutes. Users can perform duplicate analysis by regenerating the sensor surface. These techniques are fit to monitor stress level at home.
