Smart contact lens detects serotonin changes in tear samples collected during stress test

A probe squad led by Dr. Yangzhi Zhu, main researcher and adjunct prof astatine the Terasaki Institute for Biomedical Innovation, has developed a soft, reusable astute interaction lens arsenic portion of its broader Ocular Library for the Analysis of Tear Biomarkers (OCULAB), a teardrop bioelectronics level for noninvasive, longitudinal biochemical monitoring done the ocular aboveground and teardrop film. In this study, the level was utilized to measurement serotonin straight from tears arsenic a proof-of-concept people for monitoring stress-related physiological changes.
