    Fast histological assessment of adipose tissue inflammation by label-free mid-infrared optoacoustic microscopy by Vito Ko, Marie C. Goess, Lukas Scheel-Platz, Tao Yuan, Andriy Chmyrov, Dominik Jüstel, Jürgen Ruland, Vasilis Ntziachristos, Selina J. Keppler, Miguel A. Pleitez

    Published 2023-12-01
    “…Nevertheless, due to the strong optical absorption of water in biological tissues, conventional mid-IR microspectroscopy has been limited to dried thin (5–10 µm) tissue preparations and, thus, it also requires time-consuming steps—comparable to conventional imaging techniques. Here, as a step towards label-free analytical histology of unprocessed tissues, we applied mid-IR optoacoustic microscopy (MiROM) to retrieve intrinsic molecular contrast by vibrational excitation and, simultaneously, to overcome water-tissue opacity of conventional mid-IR imaging in thick (mm range) tissues. …”
