摘要： A molecular filtration device and method of use capable of filtering and purifying molecules of a particular characteristic, wherein the amount of molecule to be filtered may be in the nanogram range and may be dispersed in a relatively large volume of solution. The resultant elution may include a relatively high concentration of desired molecule, due to a relatively small volume.

摘要： A blood plasma and blood cell separation device includes a first body, a blood plasma separation membrane and a second body. The first body has an injection port. The blood plasma separation membrane is disposed on the first body. The second body is movably assembled to the first body and has a collecting stage. The collecting stage has a collecting surface and a sampling recess on the collecting stage. When a blood enters the blood plasma separation membrane from the injection port of the first body, a blood plasma in the blood plasma separation membrane is separated by a capillary force between the collecting stage of the second body and the blood plasma separation membrane, and the blood plasma enters in the sampling recess by a relative movement between the first body and the second body.

摘要： The present invention relates to a method for impregnating a filter having pores suitable for retaining particles within them that may be present in a flow of air suitable for passing through the filter, according to which the filter made up of a polymer membrane is impregnated with one or more organometallic salts by applying a treatment using supercritical CO2, the metal M of each salt being chosen from among the group of rare earths, yttrium, scandium, chromium, or a combination thereof. The invention also relates to the obtained filter and an associated method for the collection and quantitative analysis of nanoparticles.
