摘要： A complex coacervate delivery system is provided which encapsulates lipophilic nutrients such as, for example, fish oils high in omega-3 fatty acids. The complex coacervate delivery system protects the lipophilic nutrient from degradation, e.g., oxidation and hydrolysis, and also reduces or eliminates the unpleasant taste and odor of the lipophilic nutrient. The complex coacervate delivery system upon ingestion is operative to substantially release the lipophilic nutrient in the lower gastrointestinal tract in a pH-controlled manner. The complex coacervate delivery system may be included in a food or beverage product having a pH value within the range of about 1.5 to about 5.0.

摘要： The present invention provides inventive polyol-based polymers, materials, pharmaceutical compositions, and methods of making and using the inventive polymers and materials. In certain aspects of the invention, an inventive polymer corresponds to a polymer depicted below. Exemplary inventive polymers includes those prepared using polyol units (e.g., xylitol, mannitol, sorbitol, or maltitol) condensed with polycarboxylic acid units (e.g., citric acid, glutaric acid, or sebacic acid). The inventive polymers may be further derivatized or modified. For example, the polymer may be made photocrosslinkable by adding methacrylate moieties to the polymer.

摘要： The present invention generally relates to polymers and macromolecules, in particular, to block polymers useful in particles such as nanoparticles. One aspect of the invention is directed to a method of developing nanoparticles with desired properties. In one set of embodiments, the method includes producing libraries of nanoparticles having highly controlled properties, which can be formed by mixing together two or more macromolecules in different ratios. One or more of the macromolecules may be a polymeric conjugate of a moiety to a biocompatible polymer. In some cases, the nanoparticle may contain a drug. The moiety, in some embodiments, may have a molecular weight greater than about 1000 Da; for example, the moiety may include a polypeptide or a polynucleotide, such as an aptamer. The moiety may also be a targeting moiety, an imaging moiety, a chelating moiety, a charged moiety, or a therapeutic moiety. Another aspect of the invention is directed to systems and methods of producing such polymeric conjugates. In some embodiments, a solution containing a polymer is contacted with a liquid, such as an immiscible liquid, to form nanoparticles containing the polymeric conjugate. Other aspects of the invention are directed to methods using such libraries, methods of using or administering such polymeric conjugates, methods of promoting the use of such polymeric conjugates, kits involving such polymeric conjugates, or the like.

摘要： The present invention provides lipidoids that can be used to modulate the immune response in a subject. Lipidoids are prepared by the conjugate addition of an amine to an acrylate to acrylamide. The lipidoids form complexes or particles with an immunostimulatory polynucleotide, which are then administerd to a subject. Such compositions have been found to stimulate the production of cytokines and increase both humoral and cell-mediate immune response. The invention also provides pharmaceuti-cal compositions thereof and methods for using the same.
