Fabrication approaches have been previously used in two-dimensional (2D) micropattemed model systems and have led to insights on the effect of cell-cell and cell-polymer scaffold interactions on hepatocyte and endothelial cell fate. Extending these studies, the application of 3D fabrication techniques may also prove useful for studying structure-function relationships in model tissues.

In this section, we focus on the strategies of controlling nanoparticle assemblies through functionalized polymer scaffolds, starting from interparticle spacing in bulk aggregates to 3-D morphologically controlled hierarchical nanostrucmres. 

Porous, biodegradable polymer scaffolds seeded with cells have been used to determine the feasibility of regenerating a number of organs. The goals and specific problems associated with regenerating several different organs are outlined below.
