There is an increasing demand to develop bioprinting modalities that enable high-fidelity fabrication of 3D hydrogel structures that closely correspond to the envisioned design. In this work, we performed a systematic, in-depth characterization and optimization of embedded 3D bioprinting to create 3D gelatin-methacryloyl (gelMA) structures with highly controlled fidelity using Carbopol as suspension bath. The role of various embedded printing process parameters in bioprinting fidelity was investigated using a combination of experimental and theoretical approaches. We examined the effect of rheological properties of gelMA and Carbopol at varying concentrations, as well as printing conditions on the volumetric flow rate of gelMA bioink. Printing speed was examined and optimized to successfully print gelechniques. This robust platform could further expand the application of bioprinted soft tissue constructs in a wide variety of biomedical applications.DNA has become a popular soft material for low energy, high-density information storage, but it is susceptible to damage through oxidation, pH, temperature, and nucleases in the environment. Here, we describe a new molecular chemotype for data archiving based on the unnatural genetic framework of α-l-threofuranosyl nucleic acid (TNA). Using a simple genetic coding strategy, 23 kilobytes of digital information were stored in DNA-primed TNA oligonucleotides and recovered with perfect accuracy after exposure to biological nucleases that destroyed equivalent DNA messages. We suggest that these results extend the capacity for nucleic ac
