Coumarin-Based Photodegradable Hydrogels Enable Two-Photon Subtractive Biofabrication at 300 mm s-1

Spatiotemporally controlled two-photon photodegradation of hydrogels has gained increasing attention for high-precision subtractive tissue engineering. However, conventional photolabile hydrogels often have poor efficiency upon two-photon excitation in the near-infrared (NIR) region and thus require high laser dosage that may compromise cell activity. As a result, high-speed two-photon hydrogel erosion in the presence of cells remains […]

High-resolution bioprinting

Since the inception of 3D printing in the 1980s, there have been remarkable advancements that have given rise to a wide array of technologies. In the field of bioprinting, many of these technologies are being leveraged to embed living cells into precisely defined 3D structures. Droplet- and extrusion-based bioprinting, two of the earliest techniques, have […]
