Extended Data Fig. 1: Stiffness-dependent MMUS imaging in a polyacrylamide phantom.
From: Magneto-acoustic protein nanostructures for non-invasive imaging of tissue mechanics in vivo
(a) MMUS images and SBR quantification of polyacrylamides with stiffnesses ranging from 74 Pa to 14,095 Pa. MMUS imaging was performed using 0.8 nM MGVs (n = 4 independent experiments). Min and max on color bars represent 0 and 10000 arbitrary units, respectively. Scale bars, 1 mm. (b) Comparison of the MMUS signal quantification (SBR) in different hydrogels of similar stiffness (n = 5 for agarose, n = 4 for polyacrylamide). All points represent independent experiments, and line and error bars represent mean ± s.d.
