    标题:Flow controlled synthesis of bottlebrush macromolecules
    发明人:GUIRONNET DAMIEN S; WALSH DYLAN J
    权利人:UNIV ILLINOIS
    摘要:Shape, size and composition are nature's most fundamental design features, enabling highly complex functionalities. Despite recent advances, the independent control of shape, size and chemistry of macromolecules remains a synthetic challenge. Herein reported is a scalable methodology to produce large well-defined macromolecules with programmable shape, size and chemistry that combines reactor engineering principles and controlled polymerizations. Specifically, bottlebrush polymers with conical, ellipsoidal and concave architectures are synthesized using two orthogonal polymerizations. The chemical versatility is highlighted by the synthesis of a compositional asymmetric cone. The strong agreement between predictions and experiments validate the precision that this methodology offers.

    标题:Aerodynamically light vaccine for active pulmonary immunization
    发明人:SMALL PARKER; BENDER BRADLEY S
    摘要:Improved aerodynamically light particles for vaccine delivery to the pulmonary system, and methods for their synthesis and administration are provided. In a preferred embodiment, the aerodynamically light vaccine:) are made of a biodegradable material and have a tap density less than 0.4 g/ml and a mass mean diameter between 5 μm and 30 μm. The particles may be formed of biodegradable materials such as biodegradable polymers. For example, the particles may be formed of a functionalized polyester graft copolymer consisting of a linear .alpha.-hydroxy-acid polyester backbone having at least one amino acid group incorporated therein and it least one poly(amino acid) side chain extending from an amino acid group in the polyester backbone. In one embodiment, aerodynamically light vaccine particles having a large mean diameter, for example greater than 5 μm, can be used for enhanced delivery of a vaccine agent to the alveolar region of the lung. The aerodynamically light vaccine particles incorporating an immunizing agent may be effectively aerosolized for administration to the respiratory tract to permit systemic or local delivery of wide variety of immunizing agents.
