Research Abstract

Salivary biomarker such as cortisol and dehydroepiandrosterone are increasingly used as an index of the body' s neuroendocrine response to stressors. We developed and evaluated a sensor for biomarker detection using a lipid/polymer membrane or antigen-antibody reactions. A miniaturized sensor chip including lipid/polymer membrane was fabricated. It was indicated that the sensor chip can provide sensing performance with low sample volume and short-term analysis.
