Cell Scaffolds and Biomimetics

Shown below is a series of structures fabricated by means of the direct laser writing technique with Photonic Professional systems in various biocompatible materials and hydrogels. Typical topics of interest which are under investigation are the study of cell migration or stem cell differentiation. The 3D tailored environment acts as an artificial extracellular matrix, i.e., a scaffold for the cells.

Another exemplified application is the fabrication of structures demonstrating the bio-inspired phenomenon of dry adhesion, often referred to as Gecko-Effect. Within this context of biomimetics, other studies like that of the Lotus plant, Salvinia plant or shark skin are of interest and can directly be fabricated with just one fabrication step by multi-photon lithography.
