  • Publication number: 20240024251
    Abstract: A unique class of perfluorocarbon-free Dextran-based oxygen nanobubbles (DONBs) and formulations thereof. The critical components in the formulation are chosen among the U.S. Food, and Drug Administration's (FDA) approved compounds, which provide a biocompatible environment for incorporating pharmaceutical agents. Moreover, the nanobubbles are fabricated with simple sonication and homogenization method that easily fulfills the current good manufacturing practices (cGMP) requirements, which will promote scaleup production for commercial manufacturing. The formulated DONBs release oxygen over an extended period to keep the partial pressure of oxygen within the inner retina high and thus preserve retinal tissue from ischemia.

  • Publication number: 20240003877
    Abstract: Devices, systems, and methods are provided for magnetic focus enhanced lateral flow assays. The devices and systems are ultrasensitive and provide for the visual detection of the presence or absence of one or more target analytes—which may include pathogens, proteins, or even molecules smaller than the foregoing—even when such analytes are only present in very limited amounts. The devices and systems include an immunostrip with a magnet positioned adjacent thereto, and magnetic probes specific to a target analyte that bind to the target analyte with specificity if present within a fluid sample to be tested. Methods are also provided for detecting one or more target analytes using magnetic focus, such methods including a step of controlling movement of a target analyte complex on an immunostrip incorporating a magnetic field, where such control slows a flow of the target analyte complex through a capture area on the immunostrip.

  • Publication number: 20230372581
    Abstract: Herein is described an oxygen nanobubbles-embedded hydrogel (ONB-G) with carbopol for oxygenation of wounds to accelerate the wound healing process. We integrate carbopol hydrogel and dextran-based ONBs, to prepare ONB-G that can hold oxygen and release it to accelerate wound healing. Oxygen release tests showed that the proposed ONB-G could maintain oxygen in the hydrogels for up to 34 days. Also, fluorescence studies indicated that the ONB-G could maintain the high oxygen levels for up to 8 weeks. Histological evaluation of tissues with a pig model with incision and punch wounds showed that treatment with ONB-G exhibited improved healing compared with hydrogel without ONBs or treated without gel. Our studies show that dextran-shell ONBs embedded in a gel (ONB-G) has the potential to accelerate wound healing given its oxygen holding capacity and release properties.
