  • Patent number: 11098301
    Abstract: The present disclosure is directed to systems, devices and methods for nucleic acid or protein purification and imaging. A system is provided including a cartridge comprising a sample input area configured to hold a sample, comprising a plurality of hybridized complexes comprising a plurality of target molecules each hybridized with probes and a plurality of non-hybridized probes. The cartridge may also include a first binding chamber configured with first magnetic beads to receive and bind the sample, a first elution channel configured to receive the first magnetic beads and elute the sample from the first magnetic beads, a second binding chamber configured with second magnetic beads to receive and bind the sample, a second elution channel configured to receive the second magnetic beads and elute the sample from the second magnetic beads, and a binding area configured to receive the eluted sample and hold molecules for imaging.

  • Patent number: 9279190
    Abstract: The present invention relates to a method for preparing a diamond carbon membrane on a surface of stainless steel, including: immersing the pretreated stainless steel into a solution of a biomass-derived carbonaceous mesophase in ethanol for several minutes, prior to taking out and air drying; or alternatively, spraying the solution of the biomass-derived carbonaceous mesophase in ethanol onto the stainless steel surface, to provide a layer of the biomass-derived carbonaceous mesophase film adhered on the stainless steel surface upon full volatilization of the solution on the surface; and then carrying out thermal treatment under a hydrogen atmosphere, to prepare the diamond carbon membrane on the stainless steel surface.
