  • Publication number: 20190136187
    Abstract: A blood isolation and extraction method includes: providing a predetermined amount of blood; utilizing a platelet filter unit to filter the predetermined amount of blood to generate a filtered blood; utilizing a plasma separation unit to divide the filtered blood into a plasma layer and a blood cell layer for separating blood cells from blood plasma; and extracting the blood plasma from the plasma layer and the blood cells from the blood cell layer. In another embodiment, the blood isolation and extraction method further includes: providing a platelet-washing unit to wash the platelet filter unit with a solution to produce a platelet solution; and mixing the platelet solution with the blood plasma to produce a platelet and plasma mixed solution.

  • Publication number: 20180133687
    Abstract: An amphiphilic film structure includes an amphiphilic film, a hydrophobic material layer formed as a first material layer and a hydrophilic material layer formed as a second material layer. The hydrophobic material layer is made of at least one hydrophobic monomer material and the hydrophilic material layer is made of at least one hydrophilic monomer material. The hydrophilic material layer is attached to a predetermined surface for absorbing moisture thereof which can be diffused via the hydrophobic material layer.

  • Publication number: 20150240034
    Abstract: A method for forming nanoscale microstructures by solvent etching comprises steps of preparing nanospheres and placing the nanospheres onto a surface of a liquid and allowing the nanospheres to be regularly arranged to form a template. The template is transferred to the photocurable adhesive of the substrate to form a photocured adhesive layer. After photocuring the photocurable adhesive to form a photocured adhesive layer, the substrate is removed and the template and the photocured adhesive layer are placed into a solvent with insignificant polarity to perform etching by dissolving the template with the solvent to form the nanoscale microstructure on the photocured adhesive layer. The method does not require large-scale machines, expensive equipments, and long processing time of molecular self-assembly. In addition to the above advantages, this method is not limited by size of substrates.

  • Publication number: 20150240863
    Abstract: A microstructure sucker device includes a substrate, a microstructure and an operation surface. The microstructure is arranged on the first surface of the substrate to form a microstructure sucker layer. The operation surface is provided on the second surface of the substrate and corresponds to the surface sucker layer. An operation method of the microstructure sucker device includes: aligning the sucker layer with a predetermined surface; attaching the microstructure sucker layer to the predetermined surface; pressing the microstructure sucker layer to discharge an amount of air from the microstructure sucker layer to suck the predetermined surface; pulling an edge of the microstructure sucker layer to separate the microstructure sucker layer from the predetermined surface.
