The invention discloses a functionalised chromatography medium, comprising: i) at least one non-woven layer (10) of polymeric nano fibres (20) comprising a plurality of nanofibre-nano fibre fusion points (30); ii) a grafted polymer coating covering the polymeric nanofibres and the nanofibre-nanofibre fusion points; iii) a plurality of ligand groups covalently bound to the grafted polymer coating, wherein the ligand groups are capable of interacting with a target biomolecule.

Composite material comprising a support material and at least one polymeric layer, wherein the at least one polymeric layer is present in form of a polymeric mesh and is comprising at least one non-adsorbing/non-adsorptive polymer with respect to a target compound, and wherein said composite material further comprises sites which are adsorbing/adsorptive for an impurity compound; and a combination of at least one first adsorbent and at least one second adsorbent, wherein the at least one first adsorbent comprises at least one composite material comprising at least one adsorbing/adsorptive polymer, or at least one non-adsorbing/non-adsorptive polymer, or at least one adsorbing/adsorptive polymer together with at least one non-adsorbing/non-adsorptive polymer.

An object of the present invention is to provide a material which can remove an activated leukocyte-activated platelet complex with high efficiency. The present invention provides a material for removing an activated leukocyte-activated platelet complex, the material being a water-insoluble carrier to the surface of which carrier a compound(s) having a charged functional group(s) is(are) bound, wherein an extending length ratio of the surface is 4 to 7.

This disclosure provides polyamine sorbent compositions for the separation of metals from aqueous solutions. The polyamine sorbent compositions comprise a silica support, an aminosilane bound to the silica support, an epoxysilane bound to the silica support, and a polyamine where the polyamine is chemically tethered onto a solid silica support through via the epoxysilane. The polyamine may be further stabilized within the bulk sorbent through hydrogen bonding interactions with the aminosilane. The sorbent compositions resist leaching by H.sub.2O in an aqueous stream containing heavy oxyanion-based (and other) metals and demonstrate stability over a pH range of 2-14. The sorbent compositions are useful for the separation of metals from aqueous solutions. The cationic heavy metals are captured by the co-existing amine groups (NH.sub.2, NH, N) from the polymeric network while additional metal capture capacity is derived from the introduction of a secondary silane linker.

The present invention relates to a super absorbent resin, and the super absorbent resin can exhibit a fast absorption rate and high gel strength even in a partially swollen state through the size optimization of partially swollen gel particles. Therefore, the use of the super absorbent resin can effectively prevent a rewetting phenomenon.

Disclosed herein are peptoids and related compounds, including peptoid affinity ligands for binding and/or purifying immunoglobulins, immunoglobulin fragments or immunoglobulin fusion proteins thereof.
