According to the present invention, a process for treating cultured cells is provided, which comprises the steps of: a) providing planar, two-dimensional objects ('flakes'), wherein these objects comprise a material which, upon application of an extrinsic stimulus, is transferred from the planar state into a rolled state, b) providing cells on said flakes, and c) transferring the flakes from the planar state into a rolled state by application of said extrinsic stimulus. |
