Abstract
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.
