Beckman Institute researchers have developed an innovative method to clearly visualize the structure and chemical composition of a human cell. Their study, published November 14 in the journal Proceedings of the National Academy of Sciences, utilizes signal detection to advance the field of chemical imaging.
Researchers have long been interested in determining what cells are made of and where cell structures reside. Optical microscopy uses visible light to illuminate surface-level features like color and structure, while chemical imaging uses invisible infrared (IR) light to reveal a sample’s inner workings… Continue reading.
Bioengineers at the University of Illinois funded by the National Institute of Biomedical Imaging and Bioengineering (NIBIB) have combined standard microscopy, infrared light, and artificial intelligence (AI) to assemble digital biopsies that identify important molecular characteristics of cancer biopsy samples without dyes or labels.
The standard for cancer biopsies is treating the tissue to be tested with staining solutions that reveal cellular details that help a pathologist identify whether a sample is cancerous, and if so, give some idea of cancer severity. Fixing and staining the tissue can take several hours, and although pathologists are very skilled, making a diagnosis based on the size and shape of cells—enhanced by the staining process—can differ between individuals… Continue reading.
WASHINGTON, D.C.— The American Institute for Medical and Biological Engineering (AIMBE) has announced the pending induction of Rohit Bhargava, Ph.D., Professor and Bliss Faculty Scholar, Bioengineering, University of Illinois at Urbana-Champaign, to its College of Fellows. Dr. Bhargava was nominated, reviewed, and elected by peers and members of the College of Fellows For pioneering the development of chemical imaging technology and the use of optical spectroscopic methods for digital pathology.
