    Abstract: A three-dimensional microwell system that supports long term pluripotent cell culture and formation of homogeneous embryoid bodies (EBs) is described. Microwell-cultured pluripotent cells remain viable and undifferentiated for several weeks in culture and maintain undifferentiated replication when passaged to Matrigel®-coated, tissue culture-treated polystyrene dishes. Microwell-cultured pluripotent cells maintain pluripotency, differentiating to each of the three embryonic germ layers. Pluripotent cell aggregates released from microwells can be passaged for undifferentiated replication or differentiated to monodisperse EBs. The ability to constrain pluripotent cell growth in three dimensions advantageously provides for more efficient, reproducible culture of undifferentiated cells, high-throughput screening, and the ability to direct pluripotent cell differentiation by generating monodisperse EBs of a desired size and shape.

    Abstract: Disclosed is a thermoreversible synthesis of a new type of material made by embedding a colloidal population within a thermo-reversibly gelled polymer. The polymer may be a physically cross-linked PVA hydrogel. PVA hydrogels are non-toxic, biocompatible, mechanically robust, and elastic. The present invention TGCCA diffraction is similar to that of photo-polymerized PCCA. The present invention TGCCA can be irreversibly covalently cross-linked using glutaraldehyde. The cross-linked TGCCA can be made responsive to chemical stimuli by functionalizing the hydrogel hydroxyl groups. The diffraction of carboxyl or amine functionalized TGCCA was monitored as a function of the pH and determined diffraction wavelengths titrate with the pKa of the functional group. It was also demonstrated that TGCCA could be fabricated in arbitrarily large volumes and shapes. The present invention method fabricates inexpensive homogenously diffracting chemically modifiable TGCCA.

    Abstract: Random arrays of single molecules are provided for carrying out large scale analyses, particularly of biomolecules, such as genomic DNA, cDNAs, proteins, and the like. In one aspect, arrays of the invention comprise concatemers of DNA fragments that are randomly disposed on a regular array of discrete spaced apart regions, such that substantially all such regions contain no more than a single concatemer. Preferably, such regions have areas substantially less than 1 ?m2 and have nearest neighbor distances that permit optical resolution of on the order of 109 single molecules per cm2. Many analytical chemistries can be applied to random arrays of the invention, including sequencing by hybridization chemistries, sequencing by synthesis chemistries, SNP detection chemistries, and the like, to greatly expand the scale and potential applications of such techniques.

  • Publication number: 20090111703
    Abstract: The present invention provides crosslinked epoxy-functional copolymer films and microarrays built from the crosslinked epoxy-functional copolymer films. Microarrays incorporating the copolymers include a substrate on which a film of the crosslinked epoxy-functional copolymer is disposed and target molecules bound to the copolymer film. The crosslinked polymer films are well-suited for use as scaffolds for target molecules in microarrays because they provide a high density of binding sites for the target molecules, are mechanically stable, and may be coated onto a wide range of substrates.

  • Publication number: 20090111701
    Abstract: A method of preparing a substrate with a composition comprising (i) an organoborane initiator and (ii) a radical curable component disposed thereon includes the step of depositing the composition onto the substrate wherein at least one of (i) the organoborane initiator and (ii) the radical curable component is deposited onto the substrate in the form of a gradient pattern. An article comprises the substrate and the gradient pattern formed on the substrate. The gradient pattern is formed from a developed composition comprising the reaction product of (i) the organoborane initiator and (ii) the radical curable component. By forming the gradient pattern on the substrate, combinatorial and high-throughput methods of generating and testing the developed composition are possible, which enable characterization of the developed composition for various physical and chemical properties.

  • Publication number: 20090082222
    Abstract: A sensor that includes a) a silicon (Si) substrate having a surface; and b) a monolayer of oligoethylene glycol (OEG) bonded to the surface via silicon-carbon bonds. Regions of the OEG monolayer distal to the surface are functionalized with a ligand serving as a recognition element for a bioanalyte. The ligand is covalently bonded in these regions as a cycloadduct of a 1,3-dipolar cycloaddition reaction. A method of making a silicon surface that recognizes a biological specimen includes 1) hydrosilylating with a mixture that includes an oligoethylene glycol (OEG) substituted with an alkene at one end of the OEG and capped at the opposing end of the OEG and an oligoethylene glycol (OEG) substituted with an alkene at one end of the OEG and an alkyne having a protecting group at the opposing end of the OEG and 2) removing the protecting group from the alkyne; and 3) reacting the alkyne with a reagent in a 1,3-dipolar cycloaddition.

  • Publication number: 20090082224
    Abstract: The application discloses a process for making a polymer having pendant side groups comprising: (i) polymerising an olefinically unsaturated monomer functionalised with (a) an azide group optionally protected by a protecting group, or (b) an alkyne group optionally protected by a protecting group, by living radical polymerisation, most preferably RAFT, transitional metal mediated living radical polymerisation (TMM-LRP) and/or atom transfer radical polymerisation, to produce a polymer intermediate; (ii) removing, when present, at least a portion of the total number of protecting groups from the polymer intermediate; (iii) reacting the polymer intermediate with at least one pendant side group moiety functionalised with (a) an alkyne group or (b) an azide group respectively so that the alkyne and azide groups react to attach the pendant side group to the polymer. Processes for making supports comprising pendant side groups, and polymers and supports prepared by the method are also disclosed.

  • Publication number: 20090042734
    Abstract: An object of the present invention is to provide a probe array having partitioned array regions with uniform surface chemical properties. The probe array of the present invention includes a substrate having a plurality of partitioned array regions where many probes are immobilized and a separator attached to the substrate and including partitions partitioning the array regions. The above object can be achieved by attaching the separator including the partitions capable of partitioning instead of forming hydrophobic regions on a surface of the substrate by printing or chemical treatment.

  • Publication number: 20090042741
    Abstract: A microarray has a substrate and a plurality of three-dimensional microstructures formed on the substrate. Each of the three-dimensional microstructures is made with polymer material and has a plurality of reactive sites formed on its surface and interior pores. The polymer material is polymer gel or other porous polymer. The combination of three-dimensional microstructure and porous polymer material increases the surface area of the microstructure and density of the reactive sites on the surface of the microstructures. The higher density of reactive sites increases the luminescence, visibility or instrument detectability of the interaction between analytes and reactive microstructure sites on the microarray. A plurality of chemical groups are respectively attached to the reactive sites. The chemical groups each include at least one monomer. The chemical groups may have different chemical structures. A plurality of microchannels can be formed around the microstructures for isolation.

  • Publication number: 20090011946
    Abstract: A method for chemical detection is provided. In one aspect, the method comprises exposing a sample to a sequence specific polymer under conditions such that an analyte in the sample binds to the polymer. Binding of the analyte to the sequence specific polymer results in a change in a property of the sequence specific polymer that is transduced to a response transduction medium, which generates a detectable response. Another aspect provides a detection device comprising the sequence specific polymer and response transduction medium.
