Abstract
A biocompatible substrate for use as a resorbable or non-resorbable implant, graft, prosthesis, etc., has an array of projections or pits of nanometer dimensions on a surface thereof, which resist attachment of cells. Typically the projections or pits are 10-250 nm in size and at spacings of 20-500 nm. The substrate may additionally have areas where cell adhesion is promoted.
Claims14
A biocompatible substrate having a surface comprising an array of projections or pits, said projections or pits being of a size and spacing such that cells have a low tendency to attach to the surface wherein the cross-sectional dimension and/or height of each projection or pit is in the range of about 10-250 nm and the center-to-center spacing of the projections or pits is in the range of about 20-500 nm.
