Abstract
According to the present invention, an implantable device is provided, comprising a substrate on which at least one surface portion is provided. The chemical composition of the surface portion selectively enhances the cell-adhesion to the substrate.
Claims18
An implantable device comprising:
- a substrate having a surface;
- wherein a first portion of the surface of the substrate, which is used for directly contacting biological cells or tissue, comprises:
- In(x)Ga(1-x)N, where x is in the range from 0.001 to 0.999, wherein the first portion promotes cell adhesion to the substrate and directs cell growth thereon, and further defines a semiconducting component of the device.
A method for selectively promoting the adhesion and growth of cells on a portion of a surface of a substrate of an implantable device, wherein said portion is used for directly contacting biological cells or tissue, the method comprising:
- forming a layer of In(x)Ga(1-x)N on said portion, where x is in the range from 0.001 to 0.999.
