摘要:
Provided are filtration media, matrixes, and systems for liquid purification that utilize functional polymer particles. The functional polymer particles can comprise a cationic charge. Exemplary functional polymer particles comprise comprise [3- (methacryloylamino)propyl]-trimethylammonium chloride (MAPTAC) polymerized with trimethylolpropane trimethacrylate (TMPTMA).
摘要:
Ligand functionalized substrates, methods of making ligand functionalized substrates, and methods of using functionalized substrates are disclosed.
摘要:
A grafted nonwoven substrate is disclosed having average fiber sizes of 0.7 to 15 microns, and a void volume of 50 to 95%, and a polymer comprising cationic aminoalkyl(meth)acryloyl monomer units grafted to the surface of the nonwoven substrate. The article may be used as a filter element to purify or separate target materials, such as oligonucleotides or monoclonal antibodies (MAb), from a fluid mixture.
摘要:
Articles that contain a solid support with a grafted chain extending from the solid support, methods of making these articles, and various uses of the articles are described. More specifically, the grafted chain has a functional group that can react with or interact with target compound. Alternatively, the functional group on the grafted chain can react with a modifying agent to provide another group that can react with or interact with the target compound. The grafted chains are attached to the solid support through a ring-opened azlactone group. The articles can be used to purify the target compound or to separate the target compound from other molecules in a sample.
