Abstract
Thin parylene C membranes having smooth front sides and ultrathin regions (e.g., 0.01 μm to 5 μm thick) interspersed with thicker regions are disclosed. The back sides of the membranes can be rough compared with the smooth front sides. The membranes can be used in vitro to grow monolayers of cells in a laboratory or in vivo as surgically implantable growth layers, such as to replace the Bruch's membrane in the eye. The application further provides an implantable cage-like apparatus for culturing cells comprising the parylene membrane.
