TL;DR: Realizing cell-culture scaffolds that mirror the complex in vivo arrangement of ECM components is an active area of biomaterials engineering and corresponding corresponding substrates were developed that allow measurements of cellular forces in 2D on planar substrates or pillar arrays.

TL;DR: The authors summarizes the state-of-the-art with regard to 3D laser micro-and nanoprinting and explores the chemical challenges limiting its full exploitation: from the development of advanced functional materials for applications in cell biology and electronics to the chemical barriers that need to be overcome to enable fast writing velocities with resolution below the diffraction limit.

TL;DR: In this article, a review of 3D scaffold fabrication techniques, materials, architectures, biochemical functionalizations, and mechanical properties of 3-D scaffolds are discussed. But the authors focus on single cells and small cell assemblies grown in tailored synthetic 3-dimensional scaffolds fabricated by computer-based techniques.

TL;DR: The combination of three different photoresists into a single direct laser written 3D microscaffold permits functionalization with two bioactive full-length proteins that allows directed cell attachment of epithelial or fibroblast cells in 3D.

TL;DR: Three-dimensional microstructures are fabricated employing the direct laser writing process and radical thiol-ene polymerization to construct resin systems that consist of a two-photon photoinitiator and multifunctional thiols and olefins.
