标 题:Synthesis of multi-functional hyperbranched polymers by polymerization of di-or tri-vinyl monomers in the presence of a chain transfer catalyst
发明人：GUAN ZHIBIN
权利人:DU PONT
摘要:This invention concerns the synthesis of multi-functional hyperbranched polymers by free radical polymerization of di- or tri-vinyl monomers in the presence of a chain transfer catalyst and a non-peroxide free radical initiator. The low viscosity and high functionality of these polymers make them useful for automotive coatings and for photopolymerization applications.

权利人:NITTO DENKO CORP
摘要:According to the invention, there is provided a solid-phase support for nucleic acid synthesis, which is constituted of a porous copolymer particle containing a multifunctional vinyl monomer unit having two or more vinyl groups in one molecule and a monofunctional vinyl monomer unit having one vinyl group in one molecule, in which the solid-phase support has a swelling volume when soaked in acetonitrile of 3.5 ml/g or more and has a median particle diameter measured by a laser scattering particle size distribution measuring method within a range of from 50 to 120 µm. According to the solid-phase support for nucleic acid synthesis of the invention, a high-purity nucleic acid can be synthesized with a high yield.

标题 :Process for synthesis of Di(meth)acrylic acid esters

摘要:A process for the synthesis and recovery of di(meth)acrylic acid esters at a high degree of purity. Di(meth)acrylic acid esters are produced by transesterfication of (meth)acrylic acid esters of C1 to C4 alcohols with 1,n-diols (where n>=3) in the presence of a zirconium catalyst that comprises a chelate of zirconium with a 1,3-dicarbonyl compound. These catalysts can be readily separated or removed from the reaction mixture by precipitation with phosphoric acid, thus providing a convenient and inexpensive method of producing a di(meth)acrylic acid ester with a reduced level of zirconium.

标 题 :Nanoliter-scale synthesis of arrayed biomaterials and screening thereof
发明人：ANDERSON DANIEL G; LEVENBERG SHULAMIT; LANGER ROBERT S
摘要:A method of screening cell-polymer interactions. The method includes depositing monomers as a plurality of discrete elements on a substrate, causing the deposited monomers to polymerize, thereby creating an array of discrete polymer elements on the substrate, incubating the substrate in a cell-containing culture medium, and characterizing a predetermined cell behavior on each polymer element.

摘要:A highly sensitive technology enabling selective recognition of aflatoxins such as in contaminated cereal samples. Methods for the synthesis of AgNP-containing MIP membranes from the monomer mixtures containing both methacrylate monomers and oligomers as well as AgNOs solution in dimethylformamide enable the detection system. The AgNP were formed in the structure of the polymeric membranes during the pre-heating step followed by the UV-initiated polymerization. The highly selective sensor elements where MIP membranes are combined with the Ag nanostructures as signal amplifiers (LSPR-MIP nanochips) can be stored separately and used with a simple optical recognition system as selective elements of point-of-care sensor devices, even in in-field conditions. Composite plasmonic membranes provide both highly selective recognition of the target toxin and the generation of an enhanced optical signal, allowing aflatoxin B1 detection at ultralow concentrations.
