3D-Microfabrication of Polymer-Protein Hybrid Structures with a Q-Switched Microlaser

We demonstrate the feasibility of an inexpensive microchip laser source to fabricate 3D-polymer and protein microstructures based on two photon absorption of a commercial available photoinitiator. The voxel length was determined by an ascending voxel method and was as small as of the resolution limit. This technique was used to generate 3D polymer-protein-hybrid microstructures, where the polymer structure serves as a robust backbone for the protein structure.
