US Patent 7135172 - Buckpaper for Eye Repair

This patent owned by NASA proposes a use of buckypaper (i.e. 2D mesh of carbon nanotubes) as a carrier to support stem cell treatment of damaged or diseased cells of an eye's retinal system. Claim 1 reads:

1. A method for preparing a retinal system of an eye for repair, the method comprising: providing a support material, comprising bucky paper having a selected thickness and a selected porosity, as a patch having a selected size; transferring at least one of (i) a retinal pigment epithelial cell, referred to as an RPE cell, (ii) an iris pigment epithelial cell, referred to as an IPE cell and (iii) a stem cell, to the support material, to provide a cell-covered support material; and attaching the cell-covered support material to a selected region in a sub-retinal space of an eye that is to be repaired.
