  • Patent number: 10276885
    Abstract: A manufacturing method of a proton exchange membrane is provided, which includes the steps as follows. The hydroxyl groups are disposed on the surface of a substrate by a hydrophilic treatment. The hydroxyl groups on the substrate are chemically modified with a coupling agent by a sol-gel process. The substrate is exposed to an amino acid with a phosphonate radical so that the amino acid containing a phosphonate radical can be chemically bonded with the coupling agent. The chemically bonded substrate is immersed in phosphoric acid for absorbing the phosphoric acid. The substrate blended with the phosphoric acid is placed between at least two leak-proof films for the purpose of preventing the leakage of the absorbed phosphoric acid.

  • Publication number: 20180230416
    Abstract: A cell chip including first and second substrates and a dye dialysis layer disposed therebetween is provided. A cell-assembly region of the dye dialysis layer is disposed corresponding to a first hole of the first substrate, includes second holes and is configured to contain a sample solution containing cells. A size of the second hole is smaller than that of the cell. The cells are arranged on the cell-assembly region in a single layer manner. When a dye enters into the cell-assembly region via the first hole, the dye diffuses from the cell-assembly region to the micro-channel structure due to a concentration difference between the dye and a washing solution in the micro-channel structure. Thereby, the cells are dyed. Also, the washing solution passes in and out the cell chip via the second holes to accelerate the dye diffusion, and a high efficiency dynamic dialysis staining for cells is achieved.
