| abstract |
The present invention provides a device adapted for implantation in a mammalian body which is coated with a membrane comprising a closely packed array of self-assembling amphiphilic molecules and receptor molecules, the receptor molecules being such that the attachment of specific cells to the membrane is enhanced or avoided. For example the receptor molecules may be directed against fibronectin, vitronectin, endothelial cells, or epithelial cells. It is also preferred that the membrane coating includes a plurality of ion channels such as gramicidin. |
