Current Limitations in 3D Bioprinting
Extrusion-based bioprinting is a commonly used method where a bioink is dispensed from nozzles to construct a scaffold layer-by-layer in continuous filaments. However, it faces challenges in printing complex structures, and it cannot create hollow structures due to collapsing risks. Additionally, its resolution is limited to approximately 200 microns, making it unsuitable for mimicking the human capillary network.
To address these limitations, two-photon polymerization (2PP) emerges as a high-resolution 3D printing technique.
Two Photon Polymerization
In the cutting-edge realm of two-photon polymerization (2PP), a specialized laser brings to life highly detailed and precise structures with astonishing nanoscale resolution. What sets 2PP apart from traditional 3D printing methods is its unique process. As the laser beam targets a specific point within a photosensitive material, a fascinating phenomenon occurs – two photons are simultaneously absorbed at that spot, sparking the polymerization reaction exclusively at the exact location where the laser concentrates its energy.
Aptly known as the "voxel," this focal point forms the foundation of the "VoxCell" technology. Harnessing the power of the voxel, we unlock the capability to craft intricate three-dimensional structures with unparalleled precision, propelling us into new frontiers of tissue engineering. By using 2PP in tissue engineering, we can embed a vascular system within the constructs, crucial for cell survival and growth. With its impressive capabilities, 2PP opens up new possibilities for creating complex tissue models with enhanced precision and functionality.
