Nanopillars can be defined on a substrate, and metal deposited on the nanopillars. A thermal treatment can reflow the metal on the nanopillars forming metallic bulbs on the top end of the nanopillars. These structures can have enhanced optical detection when functionalized with biological agents, or can detect gases, particles and liquids through interaction with the metal layer on the nanopillars. | 03-10-2016 |
20160101401 | Flow Cell Array and Uses Thereof - Apparatus and methods for using a flow cell array are provided herein. A method includes determining placement of one or more reaction sites on a first component; providing a material for the one or more reaction sites in one or more surface channels of the first component; connecting the first component to a second component to form an array, wherein the one or more surface channels of the first component connect the one or more reaction sites with one or more vias, and wherein the second component comprises the one or more vias connected to multiple sub-surface channels; and aligning the one or more surface channels of the first component with the one or more vias of the second component to form a connection between the first component and the second component. | 04-14-2016 |
20160108392 | SOLID-CORE RING-MAGNET - A solid-core ring-magnet having one or more cavities is provided. The magnet can have an overall cylindrical shape or a rectangular-prism shape. In either case, a portion of cavity walls of the magnet are ring shaped, causing the magnetic field lines to emanate from the magnet in the shape of a ring. The diameter of the ring shaped cavities can be constant throughout, constant through a portion of the cavity, variant throughout, or variant through a portion of the cavity. The cavities open to the end of the magnet, and terminate toward the core of the magnet. Also provided are systems and kits having solid-core ring-magnets. Methods of purifying a macromolecule using the solid-core ring-magnets are also provided. | 04-21-2016 |
