    Spectral angle mapping (SAM) allowed differentiation of cells imaged using hyperspectral dark-field microscopy. Cells below the threshold spectral angle are marked as positive using a green outline; cells above the threshold are marked as negative with a red outline. Isolate cell detection shows positive E. coli 157:H7 (a) and Listeria monocytogenes (b). A slide with both pathogens depict E. coli (c) at positive (48) and negative (65), and Listeria monocytogenes (d) at positive (66) and negative (47).

    Aided by deep learning, hyperspectral imaging facilitates high-speed single-cell pathogen detection with no critical volume and little prep.
