    Abstract: We describe methods for synthesis and formulations of stable elastomeric negative acoustic contrast particles with controllable compressibility and density. These elastomeric negative acoustic contrast particles have a density/compressibility ratio that is less than that of water and therefore exhibit negative acoustic contrast under acoustic radiation exposure. This negative acoustic contrast allows our elastomeric negative acoustic contrast particles to be acoustically manipulated (e.g. separated) differently from other components (e.g. cells) within an aqueous solution. This disclosure also describes methods for biofunctionalization of the elastomeric negative acoustic contrast particles and as an example their use as platforms for bioassays. Potential applications of these elastomeric negative acoustic contrast particles include sensitive bioassays based on acoustic flow cytometry and other types of techniques that utilize acoustic fields, including ultrasound imaging and ultrasound triggered drug delivery.

    Abstract translation: 我们描述了具有可压缩性和密度的稳定的弹性体负声学对比粒子的合成方法和配方。 这些弹性体负声学对比颗粒的密度/压缩比小于水的密度/压缩比,因此在声辐射暴露下呈现负的声学对比度。 这种负声学对比度允许我们的弹性体负声学对比粒子与水溶液中的其它组分(例如细胞)不同地被声学操纵(例如分离)。 本公开还描述了弹性体负声学对比粒子的生物功能化的方法,并且作为其用作生物测定平台的实例。 这些弹性体负声学对比粒子的潜在应用包括基于声流式细胞术的敏感生物测定和利用声场的其他类型的技术,包括超声成像和超声触发药物递送。

    Abstract: The disclosure provides a simple and effective way of synthesizing robust organic- inorganic hybrid gels and ultra-thin films using vaporization of a gel precursor. The gels are synthesized at relatively low temperature allowing the activity of the immobilized species to be maintained. The disclosure provides robust, synthetic, selective, active and/or passive transport systems in the form of functional biologically active species and mechanisms for forming them. These systems allow selective and passive or active transport of ionic, molecular and biological species through the incorporation of functional biological molecules and biomolecular assemblies in a rigid matrix.
