    Abstract: Provided are methods for enhanced sequencing of nucleic acid templates. Also provided are reaction conditions that increase branching fractions during polymerization reactions. Also provided are compositions comprising modified recombinant polymerases that exhibit branching fractions that are higher than the branching fractions of the polymerases from which they were derived. Provided are compositions comprising modified recombinant polymerases that exhibit delayed translocation relative to the polymerases from which they were derived. Also provided are compositions comprising modified recombinant polymerases that exhibit increased nucleotide or nucleotide analog residence time at an active site of the polymerase. Provided are methods for generating polymerases with the aforementioned phenotypes and methods of using such polymerases to sequence a DNA template or make a DNA. Also provided are methods and nucleic acid sequencing systems for determining which labeled nucleotide is incorporated at a site during a template-dependent polymerization reaction.

    Abstract: Devices, systems and methods of using same where hybrid substrate materials are provided with a substantially uniform surface to provide uniformity of properties, including interaction with their environments. Uniform surfaces are applied as coatings over, e.g., hybrid metal/silica, metal/polymer, metal/metal surfaces to mask different chemical properties of differing regions of the surface and to afford a protective surface for the hybrid structure.
