Optoacoustic imaging with OMV-Dyes in vitro and in vivo. a, b Optoacoustic phantom imaging of OMV, OMV-IR780, OMV-Cy7, and OMV-Cy7.5 and their optoacoustic spectra. c Representative unmixed MSOT images of a 4T1 subcutaneous tumor mouse model intravenously injected with 100 μL of OMV-IR780, OMV-Cy7, and OMV-Cy7.5 (~ 100 µg OMVs), (n = 5). The green color shows an unmixed OMV-dye signal in the tumor region. d Quantification of panel-c: OMV-IR780, OMV-Cy7, and OMV-Cy7.5 concentrations in the tumor region measured over time
