Extended Data Fig. 6: Ex vivo liver imaging before and after fixation.
From: Magneto-acoustic protein nanostructures for non-invasive imaging of tissue mechanics in vivo
Three different groups of nanomaterials (MGVs, GVs, or MNPs) were injected intravenously into different cohorts, and after 5 minutes, the liver was extracted to take ultrasound images. Liver was fixed in 10% formalin for 48 h. B-mode images reveal the shape of the liver, xAM images show the GV signal located at the ultrasound focus, and the Δ images show the MMUS signal (n = 3 animals per group). Scale bars, 5 mm. Min and max on color bars for parula (MMUS) and grey (B-mode) colour bar range from 0 to 10000 arbitrary units, and the hot (xAM) colour bar ranges from 0 to 1000000 arbitrary units.
