Indian-origin scientist develops new tool for cancer diagnosis

Washington, May 13: Rohit Bhargava, an IIT-Delhi graduate and now with University of Illinois at Urbana-Champaign, has developed stainless staining that provides a new tool for clinicians and researchers for better diagnosis of cancer. Till date, prepared biopsy samples are stained and examined under a light microscope. Using infrared spectroscopic imaging for microscopy, Bhargava has reported the development of label-free chemical imaging to provide the same information as molecular stains. Instead of using stains, the new method measures the chemical constitution of cells and tissues directly. The outcome is that that molecular stains can be reproduced without staining the tissue but by using the intrinsic molecular contrast of the tissue and computation. The study relies on computation instead of staining to provide biopsy images.
