    Abstract: Embodiments described herein may be useful in the detection of analytes. The systems and methods may allow for a relatively simple and rapid way for detecting analytes such as chemical and/or biological analytes and may be useful in numerous applications including sensing, food manufacturing, medical diagnostics, performance materials, dynamic lenses, water monitoring, environmental monitoring, detection of proteins, detection of DNA, among other applications. For example, the systems and methods described herein may be used for determining the presence of a contaminant such as bacteria (e.g., detecting pathogenic bacteria in food and water samples which helps to prevent widespread infection, illness, and even death). Advantageously, the systems and methods described herein may not have the drawbacks in current detection technologies including, for example, relatively high costs, long enrichment steps and analysis times, and/or the need for extensive user training. Another advantageous feature provided by the systems and methods described herein includes fabrication in a relatively large scale. In some embodiments, the systems and methods may be used in conjunction with a detector including handheld detectors incorporated with, for example, smartphones (e.g., for the on-site detection of analytes such as pathogenic bacteria).

    Abstract: Embodiments described herein relate to compositions including iptycene-based structures. Some embodiments provide compositions including polymers having a backbone comprising an iptycene-based compound. Some embodiments described herein provide compositions having enhanced properties such as enhanced porosity, increased glass transition temperatures, and/or improved solubility as compared to traditional poly(aryl ether)-based compounds or traditional iptycene-based compounds. In some cases, the compositions may include various aryl ether compounds such as an aryl ether ketone incorporated into the polymer backbone. Non-limiting examples of suitable aryl ether compounds include polyaylethersulfones, polyaryletherketones, polyetherimides, and polyphenylene ethers. The compositions described herein may be useful in a wide variety of applications, including structural materials, flexible composites, ion conductors, fuel cell membranes such as proton exchanging membranes, sensors, preconcentrators, absorbents, or the like.

    Abstract: Embodiments described herein may be useful for optofluidic devices. For example, optofluidic devices using dynamic fluid lens materials represent an ideal platform to create versatile, reconfigurable, refractive optical components. For example, the articles described herein may be useful as fluidic tunable compound micro-lenses. Such compound micro-lenses may be composed of two or more components (e.g., two or more inner phases) that form stable bi-phase emulsion droplets in outer phases (e.g., aqueous media). In some embodiments, the articles described herein may be useful as light emitting droplets. Advantageously, the plurality of droplets may be configured such that light rays may modified (e.g., via stimulation of the droplets, exposure to an analyte such as a pathogen) to have a detectable emission intensity and/or angle of maximum emission intensity under a particular set of conditions.
