The present invention relates to a method of providing a graft scaffold for cartilage repair, particularly in a human patient. The method of the invention comprising the steps of providing particles and/or fibres; providing an aqueous solution of a gelling polysaccharide; providing mammalian cells; mixing said particles and/or fibres, said aqueous solution of a gelling polysaccharide and said mammalian cells to obtain a printing mix; and depositing said printing mix in a three-dimensional form. The invention further relates to graft scaffolds and grafts obtained by the method of the invention.

Graft scaffold for cartilage repair and process for making same

The invention provides a process for producing a conductive polymer, the process comprising: providing a substrate having an oxidant layer on a surface thereof, the oxidant layer containing an oxidant, a solvent or blend of solvents, and a relatively high molecular weight non-ionic surfactant; exposing the surface containing the oxidant layer to a vapor containing an aryl or heteroaryl monomer that is polymerizable to form a conductive polymer without exposing the oxidant layer to an external source of water vapor; and polymerizing the aryl or heteroaryl monomer to form a polyaryl or polyheteroaryl conductive polymer on the surface of the substrate.
