  • Filter
    Patent number: 8758542
    Abstract: The present invention relates to a membrane filter comprising a plurality of pores of substantially the same size. The membrane filter may be supported by at least one support (e.g. in the form of a support grid) and is able to handle a large flux and pressure in use. The invention also relates to a method of fabrication of such a filter membrane using a solvable mold.
    Type: Grant

    Assignee: Nanyang Technological University
    Inventors: Haiqing Gong, Longqing Chen
  • Method of aligning nanotubes
    Patent number: 8216636
    Abstract: A method of aligning nanotubes is described, where a plurality of channels is provided on a substrate (100), a suspension of nanotubes is placed on or adjacent an open surface of the channels (102) and the suspension is allowed to flow into the channels to align the nanotubes substantially parallel to the longitudinal axis of the channels (104).

  • Sample preparation integrated chip
    Patent number: 7338760
    Abstract: The present invention relates to an apparatus comprising a substrate having at least one assay station. The at least one assay station has at least a first assay station channel and at least a second assay station channel and the first and second assay station channels each separately being in communication with the at least one assay station. The apparatus has an arrangement of at least first and second multipurpose channels in communication with the first and second assay station channels, respectively. The first multipurpose channel and first assay station channel have internal surface characteristics conducive to conduction of a sample solution therethrough. There is at least one sample fluid inlet in communication with the at least first multipurpose channel, and at least one isolation-medium inlet in communication with the at least first and second multipurpose channels. The at least one second multipurpose channel has an internal surface portion non-conducive to conduction of said sample solution.
