GRAPHENE BIOSCAFFOLDS AND THEIR USE IN CELLULAR THERAPY
20230040370 · 2023-02-09 ·

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.

Solid diamond dental implant, composition and method
11478338 · 2022-10-25 ·

Pure compressed diamond (PCD), grown in a laboratory, is laser-shaped into dental implants with high tensile strength, high compressive strength, high thermal conductivity, and which are harder than any other substance on earth. PCD is harder than ceramic zirconia and harder than titanium. Because PCD is pure carbon, it is also 100% compatible with carbon-based living tissue. Unlike titanium, it does not provoke an immune response. PCD implants readily integrate into human jawbone. This drastically reduces post-surgery bone loss.
