  • Patent number: 11491227
    Abstract: The invention provides hydrogel, wherein the hydrogel has a supramolecular cross-linked network obtainable or obtained from the complexation of an aqueous composition including a host, such as cucurbituril, and one or more polymers having suitable guest functionality. One or more polymers in the aqueous composition may have a molecular weight of 50 kDa or more, such as 200 kDa or more. The hydrogel may hold a component, such as a therapeutic compound or a biological molecule. The hydrogels are suitable for use in medicine.
    Type: Grant

  • Patent number: 11425226
    Abstract: The exemplary embodiments relate to improving the user experience associated with a digital platform. A first user device configured to remotely access a digital platform may receive a first signal broadcast by a second user device. Two or more types of communication protocols that are available to use for establishing a direct communication channel between the user devices are identified. One of the communication protocols is selected and a communication channel is established between the user devices in accordance with the selected communication protocol. The first user device then receives authentication information from the second user and establishes a session with the digital platform based on the authentication information received from the second user device.

  • Patent number: 8757264
    Abstract: A wellbore fluid contains a viscosifying polymer in which portions of the polymer are connected through formation of an inclusion complex involving cucurbituril 8 (i.e. CB[8]) as host molecule. The fluid contains guest molecules with first and second guest groups covalently attached wherein at least one of the guest molecules comprises a polymer chain. The CB[8] host and the guest molecules attach together through reception of first and second guest groups within CB[8] host cavities, thereby connecting polymer chains together as a larger, supramolecular polymer and enhancing viscosity of the fluid. Polymer molecules may be synthetic polymers and guest groups may be attached to monomers before polymerization. Alternatively guest groups may be attached to existing polymers which may be polysaccharide.

  • Patent number: 8013065
    Abstract: A method for making a multi-branched polymer includes reacting a first polymeric unit with a functional cyclic compound to form a functional macroinitiator compound with a cyclic moiety. The functional macroinitiator compound is reacted with an amine functional compound to open the cyclic moiety and form a first functional group and a second functional group. To form the branched polymer, at least one of a second polymeric unit is propagated from the first functional group and a third polymeric unit is propagated from the second functional group.
