  • Patent number: 11878910
    Abstract: Water soluble graphene oxide nanoparticles (GO) are provided having graphene sheets containing carboxylic and hydroxyl groups. The diameter of the GO when present in a closed form range from about 40 nm to 120 nm. Eco-friendly methods are provided for producing the GO. Methods for reversible encapsulation of a molecule within water soluble carbon nanoparticles (wsCNP) including the GO nanoparticles are provided that allow for delivery of the wsCNP loaded with therapeutic and/or imaging agents to a subject in need by releasing the therapeutic/imaging agent upon an increase in pH above about 7.2. The wsCNP have been shown to cross the blood brain barrier in a mouse model of vascular dementia, and methods are provided for delivering the wsCNP loaded with a therapeutic and/or imaging molecule to the brain.

  • Patent number: 11831705
    Abstract: A system, method, and apparatus for transferring blood donation files are disclosed. An example system includes a collection device located at a blood donation site and a collection server located in a remote location. The example collection device is configured to store blood donation information from blood donors within a blood donation batch file located at a designated directory of a memory, and store metadata related to the blood donation information to the blood donation batch file. The example collection device also transmits the blood donation batch file to a registered user device. The example collection server is configured to determine the registered user device is available via a network connection. Responsive to determining the user device is connected, the collection server acquires the blood donation batch file from the user device and aggregates the blood donation batch file with blood donation batch files received from other registered user devices.
