Discovering Disease Secrets by Analyzing Exosomes Isolated from Tears

Going to the doctor might make you want to cry, and according to a new study, doctors could someday put those tears to good use. In an ACS Nano article published July 20, 2022, researchers report a nanomembrane system that harvests and purifies tiny vesicles called exosomes from tears, allowing researchers to quickly analyze them for disease biomarkers. Dubbed “iTEARS,” the platform could enable more efficient and less invasive molecular diagnoses for many diseases and conditions, without relying solely on symptoms. The open-access article is titled “Discovering the Secret of Diseases by Incorporated Tear Exosomes Analysis Via Rapid-Isolation System: iTEARS.”
