Dr. Sergey Alexander from the Tissue Optics and Microcirculation Imaging group (TOMI) at National University of Ireland Galway has demonstrated a novel label-free depth resolved sensing technique based on optical coherence tomography (OCT) to detect structural changes at the nanoscale. This label free approach provides new possibilities for depth resolved study of pathogenic and physiologically relevant molecules in the body with high sensitivity and specificity. It offers a powerful opportunity for early diagnosis and treatment of diseases.
