We use nonlinear lithography to structure novel biocompatible and/or biodegradable materials. The 3D structures can be used as scaffolds for the growth of new tissue.

Abstract

A matter of considerable research interest recently is the creation and structuring of biocompatible materials to enable the integration of living cells. The choice of the scaffold for cell cultivation can greatly influence the attachment, migration, and proliferation of cells. Scaffold materials that are not rejected by the body upon implantation can be selected from metals, ceramics, synthetic polymers, and biopolymers.

Micron-sized topography has been shown to play an essential role in determining cell adhesion and surface-bound characteristics influence in this way prominent cellular functions such as survival, proliferation, differentiation, migration, or mediator release. In particular, 3-dimensional (3D) cell cultures offer a more realistic micro- and local-environment where the functional properties of cells can be observed and manipulated. An important factor in the production of working tissue engineering scaffolds is the ability of a reproducible and controlled method of nanostructuring. A versatile class of scaffold production techniques which enable the fabrication of tailored structures directly from a computer data via Computer Aided Design / Computer Aided Manufacturing (CAD/CAM) are solid-free-form fabrication techniques. 3D laser nonlinear lithography has been demonstrated as a technology for the fabrication of 3D structures with high resolution capabilities.
We are investigating two different approaches to the fabrication of 3D scaffolds using nonlinear lithography. The first is the fabrication of biodegradable 3D scaffolds, which can be used for the growth of soft tissue. The second is the fabrication of permanent 3D scaffolds, for the growth of bone tissue. In this case, to assist cell growth, we are investigating the surface functionalization of these scaffolds with biomolecules such as amyloid peptides. One such structure is shown in the picture below, where a 3D structure has been fabricated using nonlinear lithography and has subsequently been functionalized with self-assembled amyloid peptide fibers.
