FUNCTIONALISING POLYMERIC MATERIALS

摘要

The invention provides a method for functionalising all or part of a surface of a structure fabricated from a crosslinkable polymeric material comprising the steps of; defining a structure in a material that is crosslinkable by undergoing a curing process; the curing process involving cross-linking of reactive functional groups in the polymeric material; performing the curing process under conditions where at least part of the surface of the defined structure is in contact with a polymeric material that is non-crosslinkable under the conditions of the curing process; removing the non-crosslinkable polymeric material from the surface of the defined structure after curing, whereby said surface comprises unreacted functional groups. The structure may be a shaped, coded, microparticle and may have attached thereto chemical moieties and/or biomolecules.
