Femtosecond laser holograpic fabrication of hydrogel cell scaffold
In order to achieve rapid fabrication of hydrogel cell scaffolds, the computer-aided holographic method was employed into the traditional femtosecond laser two-photon processing. The generation of hologram as well as the influence of its parameters on the processed cylinder microstructure was studied. Firstly, Ring-shaped Bessel-beam holograms were generated according to the Bessel light wave equation and its transmission function, of which the parameters effect on the size and quality of ring structure was analyzed. Then the generated holograms were used to process tubes with a thickness of 0.8 μm and diameters from 8 μm to 15 μm in the polyethylene glycol double acrylate (PEGDA) hydrogel. Finally, an efficient and rapid processing of hydrogel cell scaffolds was realized experimentally and the diameter of hydrogel tubes was 8 μm. This technique can remarkably improve the efficiency of femtosecond laser processing, thus has great potential in many applications such as biological culture and chemical analyses.
