The field of living materials seeks to harness living cells as microfactories that can construct a material itself or enhance the performance of material in some manner. While recent advances in 3D printing allow microbe manipulation to create bespoke living materials, the effective coupling of these living components in reinforced bioink designs remains a major challenge due to the difficulty in building a robust and cell‐friendly microenvironment. Here, a type of dual‐network bioink is reported for the 3D printing of living materials with enhanced biocatalysis capabilities, where bioinks are readily printable and provide a biocompatible environment along with desirable mechanical performance. It is demonstrated that integrating microbes into these bioinks enables the direct printing of catalytically living materials with high cell viability and maintains metabolic activity, which those living materials can be preserved and reused. Further, a bacteria‐algae coculture system is fabricated for the bioremediation of chemicals, giving rise to its potential field applications.
The preparation of dual-release pharmaceutical microfibers provides an ideal material for new biomedical applications. We describe a microfluidic spinning method for engineering heterotypic bead-on-string fibers with the ability to carry...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
