Inventors at Georgia Tech disclose a unique new instrument for multi-modal imaging of biological samples with subcellular spatial resolution. The instrument is composed of a combination of Scanning Electron Microscopy (SEM) and a new mode of Desorption Electrospray Ionization (DESI) imaging mass spectrometry. Termed BeamMap, for Beam Enabled Accurate Mapping & Molecular Analyte Profiling, provides untargeted characterization of protein, metabolite and lipid chemistry and correlation with topological features, yielding an order of magnitude improvement in the achievable resolution for electrospray based imaging. Beam Map has potential to bring about a transformative effect on many areas of biomedical sciences.
