  • Publication number: 20140296435
    Abstract: This invention provides Chelating Complex Micelles as a drug carrier. The Chelating Complex Micelles can load drugs without changing their structure, and therefore extend the half-life of drugs in the human body. The chelating complex micelles contain a metal ion core, at least one polymer, and at least one drug molecule. The metal ion is considered as a Lewis acid while polymer chain and drug molecules are referred to as Lewis bases. The drug molecule is linked to the polymer via forming coordinate bonds with metal ion, and then self-assembled to form chelating complex micelles as a drug carrier.

  • Publication number: 20140242623
    Abstract: We disclose methods and compositions for preparation of stimuli-responsive plastics that are capable of responding to chemical and/or physical signals in their environment. In one embodiment the plastics consist of patterned mixtures of poly(phthalaldehyde) polymers in which each polymer contains a different end-capping group (also called a “trigger”), responsive to a different signal. Other embodiments use different polymers and different triggers. The plastics may be homogeneous in composition, but each polymer within the plastic is capable of responding to a different signal and depolymerizing once this signal reacts with the trigger. This process of depolymerization enables the plastic to alter its physical features non-linearly to external signals: i.e., the degree of change in physical form is much larger than the intensity of the initial signal.

  • Patent number: 8613611
    Abstract: The conductive polyrotaxane of the present invention contains an electron-accepting cyclic molecule in each of its repeating unit. Since the electron-accepting cyclic molecule remains stable because of molecular interaction with a ?-conjugated oligomer molecule, the electron-accepting cyclic molecule is not dissociated during rotaxane polymerization reaction, and thus a conductive polyrotaxane of stable quality can be obtained.
