  • Patent number: 9636639
    Abstract: The present disclosure relates to a method of forming a metallic layer having pores extending therethrough, the method comprising the steps of: (a) contacting a cathode substrate with an electrolyte solution comprising at least one cation; reducing the cation to deposit the metallic layer on a surface of the cathode substrate; and (c) generating a plurality of non-conductive regions on the cathode substrate surface during reducing step (b); wherein the deposition of the metallic layer is substantially prevented on the non-conductive regions on the cathode substrate surface to thereby form pores extending through the deposited metallic layer. The present disclosure further provides a metallic porous membrane fabricated by the disclosed process.

  • Patent number: 9228977
    Abstract: A portable electrophoretic contactless conductivity detection (C4D) system for analysis on a microfluidic chip houses in one embodiment a fluidic compartment for receiving the microfluidic chip, and four detection electrodes: first and second emitting electrodes, and first and second receiving electrodes. The first emitting electrode and the first receiving electrode are adjacent to a first channel wall of the microfluidic chip, and the second emitting electrode and the second receiving electrode are adjacent to a second channel wall, where the second channel wall is opposite to the first channel wall. In an embodiment, the electrodes are provided as portions of a removable cartridge cell.

  • Patent number: 9139924
    Abstract: For forming a nickel mold, a metal and a corresponding etchant are selected such that the etchant selectively etches the metal over nickel. The metal is sputtered onto a surface of a template having nano-structures to form a sacrificial layer covering the nano-structures. Nickel is electroplated onto the sacrificial layer to form a nickel mold, but leaving a portion of the sacrificial layer exposed. The sacrificial layer is contacted with the etchant through the exposed portion of the sacrificial layer to etch away the sacrificial layer until the nickel mold is separated from the template. Subsequently, the nickel mold may be replicated or scaled-up to produce a replicate mold by electroplating, where the replicate mold has nano-structures that match the nano-structures on the template. The metal may be copper.

  • Patent number: 9007075
    Abstract: The contactless conductivity detector in one embodiment includes a microfluidic chip having a channel (102) thereon and four detection electrodes: first and second emitting electrodes (100a, 101a), and first and second receiving electrodes (100b, 101b). The channel (102) is defined by channel walls. The first emitting electrode (100a) and the first receiving electrode (100b) are adjacent a first channel wall, and the second emitting electrode (101a) and the second receiving electrode (101b) are adjacent a second channel wall, the second channel wall being opposite the first channel wall.
