Abstract: Microarrays, hybridization seals and related methods. An apparatus includes a substrate including a plurality of probes and a hybridization seal. The hybridization seal includes an evaporation barrier and a layer including walls that form a grid pattern and define a plurality of sample chambers that are to receive fluid. The layer includes a first side removably coupled to the substrate and a second side that is coupled to the evaporation barrier.

The evaporation barrier includes barrier sections that cover the probes and include one or more slits that allow the barrier sections to have a convex profile or a concave profile depending on an amount of the fluid within the corresponding sample chamber.

Abstract: A kit for biological sequencing operations includes a flow cell including a plurality of depressions having a first diameter. The kit further includes a suspension including: a liquid carrier; and a plurality of functionalized nanostructures dispersed throughout the liquid carrier. Each of the plurality of functionalized nanostructures has a second diameter that is equal to or less than the first diameter. Each of the plurality of functionalized nanostructures includes: a nanostructure core; and a plurality of primers attached to the nanostructure core. The kit further includes a plurality of mechanical loading beads having a third diameter that is greater than the first diameter.

Abstract: The present application relates to palladium catalyst composition and uses in sequencing by synthesis. In particular, the Pd catalyst composition comprises one or more macrocycles (e.g., cyclodextrin or analogs thereof) as additives for improving thermal or oxidative stability of the active Pd(0) species.

Abstract: The present invention includes methods for producing magnetic nanocrystals by using a biological molecule that has been modified to possess an amino acid oligomer that is capable of specific binding to a magnetic material.

Abstract: The invention provides nanosensors and nanosensor components for the detection of ion channel activity, receptor activity, or protein protein interactions. Certain of the nanosensor components comprise a nanoparticle and recognition domain. Following contact with cells and, optionally, internalization of the nanosensor component by a cell, the recognition domain binds to a target domain, e.g., a heterologous target domain, of a polypeptide of interest such as an ion channel subunit, G protein coupled receptor (GPCR), or G protein subunit. Ion channel activity, GPCR activity, or altered protein interaction results in a detectable signal. The nanoparticles may be functionalized so that they respond to the presence of an ion by altering their proximity. Certain of the nanosensors utilize the phenomenon of plasmon resonance to produce a signal while others utilize magnetic properties, RET, and/or ion-sensitive moieties. Also provided are polypeptides, e.g.

Abstract: An inorganic nanowire having an organic scaffold substantially removed from the inorganic nanowire, the inorganic nanowire consisting essentially of fused inorganic nanoparticles substantially free of the organic scaffold, and methods of making same. For example, a virus-based scaffold for the synthesis of single crystal ZnS, CdS and free-standing L10 CoPt and FePt nanowires can be used, with the means of modifying substrate specificity through standard biological methods. Peptides can be selected through an evolutionary screening process that exhibit control of composition, size, and phase during nanoparticle nucleation have been expressed on the highly ordered filamentous capsid of the M13 bacteriophage. The incorporation of specific, nucleating peptides into the generic scaffold of the M13 coat structure can provide a viable template for the directed synthesis of a variety of materials including semiconducting and magnetic materials.
