Sunyoung Lee Uses Force to Image of Cell Receptors

MIT researchers have found a way to glimpse interactions between molecules on the surface of a cell. By measuring the force generated by these cell surface interactions, the MIT team was able to image and measure the rate at which individual molecules join and separate from receptors on the cell surface. These interactions are not visible with traditional light microscopy.

“We were able to measure regions of strong intermolecular binding on the cell surfaces, which enabled us to map the locations of the receptors,” said Sunyoung Lee, a graduate student in the Department of Materials Science and Engineering and lead author of a paper on the work in the June 5 issue of the Proceedings of the National Academy of Sciences.

Lead author of the paper is graduate student and former Hugh Hampton Young fellow Sunyoung Lee. Continue reading on MIT News.
