International Classification:

A61K 33/04

US Classification:

977787, 424703

Abstract:

Self-assembly of nanoparticles at the interface between two fluids, and methods to control such self-assembly process, e. g. , the surface density of particles assembling at the interface; to utilize the assembled nanoparticles and their ligands in fabrication of capsules, where the elastic properties of the capsules can be varied from soft to tough; to develop capsules with well-defined porosities for ultimate use as delivery systems; and to develop chemistries whereby multiple ligands or ligands with multiple functionalities can be attached to the nanoparticles to promote the interfacial segregation and assembly of the nanoparticles. Certain embodiments use cadmium selenide (CdSe) nanoparticles, since the photoluminescence of the particles provides a convenient means by which the spatial location and organization of the particles can be probed. However, the systems and methodologies presented here are general and can, with suitable modification of the chemistries, be adapted to any type of nanoparticle.

International Classification:

C07F 9/02
C09K 11/02

US Classification:

568 14, 25230136

Abstract:

Cadmium selenide, and other quantum dot materials, can be integrated into thin films of poly(para-phenylene vinylene) (PPV) or other polymer compounds without aggregation of the nanocrystals. Solid-state photoluminescence spectra of composite materials prepared by these novel techniques reveal the effect of this greatly enhanced quantum dot-polymer interface relative to cases where the nanoparticles are aggregated, such that electronic communication and energy transfer between the nanoparticle and polymer components is made more efficient.

International Classification:

US Classification:

Abstract:

Polymer capsules from amphiphilic graft copolymers comprising reactive, hydrophobic polyolefin backbones, and hydrophilic poly(ethylene glycol) (PEG) grafts are produced by self-assembly of the polymers at the oil-water interface, and crosslinking the assembly with bis-cyclooctene PEG derivatives in conjunction with ring-open metathesis polymerization catalysts. The use of the graft copolymer architecture in capsule synthesis provides significant opportunities to tune both the surface properties, in terms of recognition, and the membrane properties, in terms of mechanical strength, encapsulation, and release.

Abstract:

Azidoaryl-substituted cyclooctene monomers and synthesized and used in the preparation of various copolymers. Among these copolymers are those prepared from ring-opening metathesis polymerization of cyclooctene, polyethylene glycol-substituted cyclooctene, and azidoaryl-substituted cyclooctene. These copolymers are useful in the formation of crosslinked films that reduce fouling of water purification membranes.

Abstract:

The present invention discloses a method of making core-shell polymer particles, comprising forming a linking-group-containing polymer by derivatizing a hydroxy-group-containing polymer, comprising hydroxy groups on adjacent carbon atoms with a linking agent, that is a compound comprising both an aldehyde moiety and an amine moiety, wherein one or more acetal moieties are formed in the linking-group-containing polymer, each acetal formed by the reaction of the aldehyde moiety in the linking agent with two hydroxy groups in the linking-group-containing polymer, wherein the amine moiety then becomes a linking group pendent from the linking-group-containing polymer, wherein the linking group is capable of reacting with a precursor group in the precursor polymer. Also disclosed are compositions comprising insoluble core-shell particles made by the method.
