Abstract

Understanding metabolism is indispensable in unraveling the mechanistic basis of biological processes. However, in situ metabolic imaging tools are still lacking. Here we introduce a framework for mid-infrared (MIR) metabolic imaging by coupling the emerging high-information-throughput MIR microscopy with specifically designed IR-active vibrational probes. We present three categories of small vibrational tags including azide bond, 13C-edited carbonyl bond and deuterium-labeled probes to interrogate various metabolic activities in cells, small organisms and mice. Our technique is uniquely suited to metabolic imaging with high information throughput. In particular, we performed single-cell metabolic profiling and large-area metabolic imaging at tissue or organ level.
