Abstract:

The combination of three different photoresists into a single direct laser written 3D microscaffold permits functionalization with two bioactive full-length proteins. The cell-instructive microscaffolds consist of a passivating framework equipped with light activatable constituents featuring distinct protein-binding properties. This allows directed cell attachment of epithelial or fibroblast cells in 3D.
