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).

Pathogen detection with hyperspectral dark-field microscopy

July 14, 2020

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