Abstract: This invention relates to a surface discovery system and high-throughput combinatorial synthesis methods for generating large numbers of diverse surface coatings on solid substrates. The system is built upon a synthon which comprises at least three elements: a chemical backbone coating on the solid substrate that comprises a copolymer (B) of at least one passive constituent (P) and at least one active constituent (A); a spacer unit (S) separating the backbone from a functional group; and a functional group (F). The methods comprise the following steps: 1) selecting a plurality of synthons so that each synthon has at least two points of diversity selected from P, A, S and F; 2) applying copolymer B onto a substrate; and 3) attaching a combination of S and F to constituent A of copolymer B. Steps 2) and 3) are performed such that different synthons are generated on localized regions of the substrate.

Abstract: The present invention relates to a surface discovery system comprising chemical compositions and high-throughput combinatorial synthesis methods for generating large numbers of diverse surface coatings on solid substrates. This surface discovery platform is built upon a fundamental chemical unit refereed to as a synthon. Each synthon comprises at least three elements: a chemical backbone coating on the solid substrate that comprises a passive (P) constituent and an active (A) constituent; a spacer unit (S) separating the backbone from a functional group; and a functional group (F). Variation of these synthon elements allows generation of large libraries surface coatings with a broad range of molecular and macroscopic properties. Further the spectrum of surfaces provided by the invention permits optimization of the wide range of solid-phase applications that involve surface immobilization of molecules.

Abstract: The invention relates to a process for coating a material surface, comprising the steps of: (a) applying to the material surface a tie layer comprising a polyionic material; (b) covalently binding a bifunctional compound comprising an ethylenically unsaturated double b3nd to the tie layer; and (c) graft polymerizing a hydrophilic monomer onto the compound comprising the ethylenically unsaturated double bond. The coated articles that are obtainable by the process of the invention have desirable characteristics regarding adherences to the substrate, durability, hydrophilicity, wettability, biocompatibility and permeability and are thus useful for the manufacture of biomedical articles such as ophthalmic devices.

Abstract: The present invention provides improved methods for conducting living/controlled polymerization on polymeric solid supports. The improved methods allow polymerization to occur directly from the non-functionalized surface of a bulk support. In addition, polymerization may be re-initiated to provide co-polymers. The disclosed methods may employ the non-nitroxide-based RAFT and ATRP control agents that allow controlled polymerization to proceed at relatively low temperatures (<80° C.). Furthermore, these improved methods may provide graft polymers with decreased levels of “in-growth” of the bulk solid support. The invention also provides substrate polymers, with improved properties for solid phase synthesis and diagnostic applications, which may be made by the disclosed methods.

Abstract: A hydrophilic ethylenically unsaturated macromonomer is disclosed that is prepared by the addition polymerization of addition polymerizable monomers that include monomers that have hydroxyl or amino functional groups, some of which may be subsequently reacted to provide (meth)acryl ethylenic unsaturation. The macromonomers may be used to form intraocular lenses in situ by polymerization of the macromonomers, and thus treat presbyopia.

Abstract: The present invention relates generally to a polymer having co-continuous architecture. More particularly, the present invention is directed to a single or plurality of polymer layers in polymeric, co-polymeric, hybrid or blend formation comprising at least one polymer layer having co-continuous architecture. The co-continuous architecture of the one or more polymers permits or otherwise facilitates accessibility of functional groups to an external environment or at least one polymeric layer. The accessible, i.e. co-continuous, nature of the functional groups, in or on the one or more polymers facilitates solid phase chemical processes, chromatography and ion exchange applications. The one or more polymers may also be used as a solid support for a range of diagnostic applications.

Abstract: The invention relates to a process for coating a material surface, comprising the steps of: (a) covalently binding a compound comprising an ethylenically unsaturated double bond to the material surface; (b) polymerizing a monomer comprising a reactive or crosslinkable group on the surface and thereby providing a primary polymer coating comprising reactive or crosslinkable groups, (c) in case of a monomer comprising a reactive group in step (b) reacting the reactive groups of the primary coating with a further compound comprising an ethylenically unsaturated double bond and graft-polymerizing a hydrophilic monomer and optionally a co-monomer having a crosslinkable group onto the primary coating obtained according to step (b) and (d) in case of crosslinkable groups being present in step (b) or (c) initiating crosslinking of said groups.
