Non‐invasive Reflectance Spectroscopy for Normal and Cancerous Skin Cells Refractive Index Determination: An <i>In Vitro</i> Study

Abstract

Refractive index characteristics show potential for cancer screening and diagnosis. The results show that optical spectroscopy is a promising, non-invasive tool for assessment of the refractive index of living biological cells in in vitro settings. Tracking changes in the refractive index allows screening of normal and abnormal cells for probable alterations in a non-invasive label-free method. Lasers Surg. Med. © 2019 Wiley Periodicals, Inc.
