A bioscaffold comprising a graphene matrix for use in cellular therapy is disclosed. In particular, a bioscaffold having a coating of dexamethasone on a three-dimensional graphene matrix is provided, wherein the bioscaffold elutes dexamethasone to reduce inflammatory responses following implantation of the bioscaffold in a subject. Having the dexamethasone released locally in the vicinity of the bioscaffold avoids the systemic side effects from conventional intravenous delivery while allowing the dexamethasone to modulate the inflammatory milieu within the transplantation microenvironment.

A method for fabricating a collagen bio-ink includes steps as follows. A first component is provided, wherein the first component is to fill a collagen powder to a first syringe. A second component is provided, wherein the second component is to fill a neutral solution or an acid solution to a second syringe. A mixing step is performed, wherein the first syringe is connected to the second syringe with a Lure lock connector and pushing back and forth to mix the first component and the second component to form a hydrogel and become a collagen bio-ink.

A device for treating orthopaedic trauma includes a device body having an exterior surface and a cannulation formed therein that extends from one longitudinal end of the device body to an opposite longitudinal end of the device body and at least one porous ingrowth material region associated with the exterior surface of the device body and fluidly coupled to the cannulation. The at least one porous ingrowth material region is configured to deliver a therapeutic agent from the cannulation to a region outside the device body.
