    摘要: This invention relates generally to composites comprising a plurality of nanostructures, and methods of making the same. In some embodiments, the composites further comprise a polymer. In some embodiments, the composites may have desirable properties such as, for example, biodegradability, biocompatibility, and/or high tensile strength. In one embodiment, the plurality of nanostructures comprises carbon nanotubes, and the polymer comprises a poly(beta-amino ester). Various methods are provided for preparing the composites. For example, the polymer and the plurality of nanostructures may, in some embodiments, be combined in a layer-by-layer process to form the composite. High throughput methods for preparing composites having different compositions also are provided for screening composites for desirable properties.

    摘要: Described herein are inventive compositions and methods relating to polymer conjugates and, in particular, to polymer conjugates having pendant side groups comprising ring moieties. In one aspect, embodiments are generally related to compositions that mimic naturally-occurring polyphenol compounds. The compositions comprise, in some embodiments, a polymer backbone having a plurality of hydroxyaromatic pendant side groups or derivatives thereof. For example, in some cases, a pendant side group may be a phenol or a substituted derivative thereof. In some cases, the pendant side group may be an oxidized hydroxyaromatic group, such as a quinone. In some embodiments, self-assembled structures comprising one or more of the polymer conjugates are provided. For example, the polymer conjugates may be combined with a complexing agent to form a particle. In some cases, a polymer conjugate may form a hydrogel. In some embodiments, the self-assembled structures may contain an agent, such as a pharmaceutically active agent. Also provided are methods and kits for forming the compositions, methods of using the compositions, and the like.

    摘要: Poly(β-amino esters) prepared from the conjugate addition of bis(secondary amines) or primary amines to a bis(acrylate ester) are described. Methods of preparing these polymers from commercially available starting materials are also provided. These tertiary amine-containing polymers are preferably biodegradable and biocompatible and may be used in a variety of drug delivery systems. Given the poly(amine) nature of these polymers, they are particularly suited for the delivery of polynucleotides. Nanoparticles containing polymer/polynucleotide complexes have been prepared. The inventive polymers may also be used to encapsulate other agents to be delivered. They are particularly useful in delivering labile agents given their ability to buffer the pH of their surroundings.
