Stable Thermally-Modulated Nanodroplet Ultrasound Contrast Agents [PDF]
Nanomaterials, 2021 Liquid perfluorocarbon-based nanodroplets are stable enough to be used in extravascular imaging, but provide limited contrast enhancement due to their small size, incompressible core, and small acoustic impedance mismatch with biological fluids.
