IRENI reveals the molecular composition of a sample

An approach involving synchrotron light allows one to obtain images that depict chemical functionality. An article was
published in Nature Methods on March 20, 2011.

To perform the technique at the Synchrotron Radiation Center (SRC) at UW-Madison, Hirschnugl and UWM scientist Michael Nasse built the Infrared Environmental Imaging (IRENI) facilty. The new technique employs multiple beams of synchrotron light to illuminate a state-of-the-art camera, instead of just one beam.

IRENI cuts the amount of time needed to image a sample from hours to minutes, while quadrupling the range of the sample size and producing high-resolution images of samples that do not have to be tagged or stained as they would for imaging with an optical microscope.

“Since IRENI reveals the molecular composition of a tissue sample, you can choose to look at the distribution of functional groups, such as proteins, carbohydrates and lipids,” Hirschmugl explained, “so you concurrently get detailed structure and chemistry.”
