摘要： In the present invention, an inorganic reactant is, or reactants are, localized with respect to a dendritic polymer by physical constraint within or by a non-covalent conjugation to the dendritic polymer. The localized inorganic reactant or reactants is/are subsequently transformed to form a reaction product which is immobilized with respect to the dendritic polymer. This immobilization occurs on a nanoscopic scale as a consequence of the combined effects of structural, chemical and physical changes without having covalent bonds between the product(s) and the dendritic container and results in new compositions of matter called dendritic nanocomposites. The resulting nanocomposite material can be used to produce revolutionary products such as water soluble elemental metals, with specific applications including magnetic resonance imaging, catalytic, magnetic, optical, photolytic and electroactive applications.

摘要： Antineoplastic dendritic polymer conjugates which are useful drug delivery systems for carrying antineoplastic agents to malignant tumors are prepared. The antineoplastic agent is encapsulated within the dendritic polymer using an ionic charge shunt mechanism, whereby, the antineoplastic agent interacts with the anionic functional groups on the surface of the dendritic polymer allowing the antineoplastic agent to be uptaken by the dendritic polymer through an association with the functional groups of the interior of the dendritic polymer. The antineoplastic dendritic polymer conjugates may be administered intravenously, orally, parentally, subcutaneously, intraarterially or topically to an animal having a malignant tumor in an amount which is effective to inhibit growth of the malignant tumor. The antineoplastic dendritic polymer conjugates exhibit high drug efficiency, high drug carrying capacity, good water solubility, good stability on storage, and reduced toxicity.

摘要： Dendritic polymers with enhanced amplification and interior functionality are disclosed. These dendritic polymers are made by use of fast, reactive ring-opening chemistry (or other fast reactions) combined with the use of branch cell reagents in a controlled way to rapidly and precisely build dendritic structures, generation by generation, with cleaner chemistry, often single products, lower excesses of reagents, lower levels of dilution, higher capacity method, more easily scaled to commercial dimensions, new ranges of materials, and lower cost. The dendritic compositions prepared have novel internal functionality, greater stability (e.g., thermal stability and less or no reverse Michael's reaction), and reach encapsulation surface densities at lower generations. Unexpectedly, these reactions of polyfunctional branch cell reagents with polyfunctional cores do not create cross-linked materials. Such dendritic polymers are useful as demulsifiers for oil/water emulsions, wet strength agents in the manufacture of paper, proton scavengers, polymers, nanoscale monomers, calibration standards for electron microscopy, making size selective membranes, and agents for modifying viscosity in aqueous formulations such as paint. When these dendritic polymers have a carried material associated with their surface and/or interior, then these dendritic polymers have additional properties for carrying materials due to the unique characteristics of the dendritic polymer, such as for drug delivery, transfection, and diagnostics.

摘要： The present invention discloses a photonic waveguide that is based on natural index contrast (NIC) principle and also discloses fabrication details thereof. Such waveguide forms the basis of a class of chip-scale micro- and nano-photonic integrated circuits (PICs). The NIC method utilizes the built-in refractive index difference between two layers of dielectric thin films of two materials, created from nano-materials that are designed for optical waveguide applications. This new class of waveguides simplifies the PIC fabrication process significantly. Based on the NIC based waveguides, which by design possess multiple photonic functionalities, PICs can be fabricated for a number of photonic applications such as arrayed waveguide grating (AWG), reflective arrayed waveguide grating (RAWG), interleaver, interferometer, and electro-optic sensor. Additionally, several other PICs can also be fabricated via tiers of integration, such as triple-phase integration where multiple optical functionalities are monolithically integrated on a chip.

摘要： Poly(ester-acrylate) and poly(ester/epoxide) dendrimers. These materials can be synthesized by utilizing the so-called “sterically induced stoichiometric” principles. The preparation of the dendrimers is carried out by reacting precursor amino/polyamino-functional core materials with various branch cell reagents. The branch cell reagents are dimensionally large, relative to the amino/polyamino-initiator core and when reacted, produce generation=1 dendrimers directly in one step. There is also a method by which the dendrimers can be stabilized and that method is the reaction of the dendrimers with surface reactive molecules to pacify the reactive groups on the dendrimers.
