    Abstract: A problem to be solved by the present invention is to provide an immunochromatographic test strip and a detection method using immunochromatography avoiding aggregation of colloidal gold conjugates while red blood cells in whole blood are agglutinated and then separated and removed in the case of using polybrene as a blood-agglutinating agent and the colloidal gold conjugates as a detection reagent. To solve the problem, the present inventers reviewed a past reagent configuration itself from a completely different viewpoint rather than selecting type and amount of polyanions and, as a result of extensive study on each element, the inventers surprisingly found that aggregation of colloidal gold can be suppressed by using a certain buffer solution without using neutralization by polyanions.

  • Publication number: 20150014243
    Abstract: An inorganic phase separation membrane and an application thereof in an oil-water separation relate to a field of a functional material technology, and more particularly to a super-hydrophilic and underwater super-oleophobic inorganic phase separation membrane with a micro-nano scale, a surface recombination, and mesh structure, wherein, a molecular sieve coating is formed on a porous substrate. The inorganic phase separation membrane can separate a variety of oils in several harsh water environments with a high efficiency, a low power loss, and a quick speed. The inorganic phase separation membrane can be used for a long time, and is easy to be reformed.

  • Publication number: 20140374339
    Abstract: An apparatus for filtering and/or purifying water preferably comprises a canister having filtration chamber formed therein and a matrix mounted in the filtration chamber for filtering and/or purifying water that passes through it. Shock absorbers preferably are provided for guarding against damage to the matrix if the apparatus is dropped. Preferably, the apparatus is provided with an inlet port to the filtration chamber, a first outlet port from the filtration chamber, and a second outlet port from the filtration chamber. Water may be pumped into the filtration chamber from the inlet port to wash away dirt and debris that may build up in the filtration chamber and then exit the filtration chamber with the dirt and debris via the second outlet port when open, thereby accomplishing removal of dirt and debris from the filtration chamber without having to backwash the apparatus for filtering and/or purifying water.
