Abstract: Methods and systems for measuring one or more properties of a soft material employ air transmitted ultrasound that is reflected from the soft material to generate a mechanical wave in the soft material. A method of measuring one or more properties of a soft material includes transmitting ultrasound through air to an interface boundary between the soft material and air. Force is applied to the soft material by reflecting the ultrasound from the soft material. A mechanical wave is generated in the soft material as a result of the force applied to the soft material. Propagation of the mechanical wave in the soft material is measured with an imaging system. One or more properties of the soft material is determined based on the measured propagation of the mechanical wave in the soft material.

Abstract: The present disclosure features, a kit, including a first compartment including a volatile fluorinated compound dissolved in a C1-6 alcohol; and a second compartment including water. When the contents of the first and second compartments are mixed, spontaneous nucleation of nanodroplets of the volatile fluorinated compound can form in the aqueous phase to provide a dispersion of nanodroplets in the aqueous phase. The nanodroplets can be used to generate nanobubbles or microbubbles in ultrasound imaging.
