    摘要: Methods and apparatus for evanescent light fluoroimmunoassays are disclosed. The apparatus employs a planar waveguide with an integral semi-cylindrical lens, and has multi-analyte features and calibration features, along with improved evanescent field intensity. A preferred embodiment of the biosensor and assay method have patches of capture molecules each specific for a different analyte disposed adjacent within a single reservoir. The capture molecules are immobilized to the patches on the waveguide surface by site-specific coupling of thiol groups on the capture molecules to photo-affinity crosslinkers which in turn are coupled to the waveguide surface or to a non-specific-binding-resistant coating on the surface. The patches of different antibodies are produced by selectively irradiating a portion of the waveguide surface during the process of coupling the photo-affinity crosslinkers the selective irradiation involving a mask, a laser light source, or the like.

    摘要: Methods and compositions for modifying the surface of a polymeric substrate are provided. In the subject methods, at least a portion of the surface of the polymeric substrate is contacted with a biofouling resistant surfactant composition. At least a portion of the surfactant molecules of the composition are end modified with a non-reactive, charged end group that is charge stable over a pH range of a bout 2 to 12. The subject methods and compositions find particular use with electrophoretic devices, such as capillary electrophoretic devices.

    摘要: A stimuli-responsive, hybrid hydrogel wherein the bulk of the polymer is made up of relatively inexpensive water soluble polymer strands crosslinked by protein domains. The responsiveness of the gel is controlled or modulated by the protein component.The physical and biological properties of the hydrogel are determined by specifically designed or engineered protein domains.The crosslinking of the protein domains to the water soluble polymers is by means of non-covalent bonding such as chelation or coordination bonding, biotin-avidin bonding, protein—protein interaction and protein-ligand interaction, or by means of covalent bonding. Methods of making and using the polymer-protein hydrogels are disclosed in this application.
