  • Patent number: 9650659
    Abstract: The present invention discloses a microfluidic photoreaction system and a method for screening a single cell organism having changed light-response characteristics. According to the present invention, an improved single cell organism can be effectively screened based on phototaxis using a microfluidic system. Specifically, easy monitoring at the cellular level is possible, and a mutant strain having an increased response and/or sensitivity to light can be easily and rapidly screened by various analyses, including statistical analysis of collected results. Thus, the present invention can be effectively used to investigate the correlation between phototaxis and photoconversion efficiency and to screen a single cell organism having increased photosynthetic efficiency.

  • Patent number: 8372385
    Abstract: An antifouling condensation curing organopolysiloxane composition is prepared by premixing a part or all of (A) a diorganopolysiloxane free of a reactive group with a part or all of (B) silica to form a premix, then mixing the premix with the remainder of (A) and (B), (C) a base diorganopolysiloxane, and (D) a silane. The composition has a good balance of low viscosity and high thixotropy, can be thickly coated in a single pass, and cures into a coating having rubber strength and surface smoothness and exhibiting satisfactory antifouling property over a long period of time.

  • Patent number: 8343084
    Abstract: A wound closure apparatus and associated methods are provided which utilize blood fluid by activating the clotting cascade of blood fluid within a substantially enclosed sterile container then introducing the blood fluid to the wound site to complete clotting. An apparatus for providing ways of inhibiting anticoagulating agents and slowing fibrin clot degradation are also disclosed. Kits are also disclosed. The invention provides a clotting cascade initiation apparatus including a substantially enclosed sterile containment chamber within which an aliquot of blood fluid, either autologous or from donor sources, can be received and retained. In preferred embodiments, the sterile containment chamber further includes a heparin binding agent which will bind heparin and remove it from the blood fluid. In further embodiments, the containment chamber will also include a procoagulating agent, wherein a clotting cascade can be initiated when the blood fluid is accepted into the sterile containment chamber.
