Ancient biomass is the main source for petrochemicals including plastics, which are inherently difficult to be degraded, increasingly polluting the earth's ecosystem including our oceans. To reduce the consumption by substituting or even replacing most of the petrochemicals with degradable and renewable materials is inevitable and urgent for a sustainable future. We report here a unique strategy to directly convert biomass DNA, at a large scale and with low cost, to diverse materials including gels, membranes, and plastics without breaking down DNA first into building blocks and without polymer syntheses. With excellent and sometimes unexpected, useful properties, we applied these biomass DNA materials for versatile applications for drug delivery, unusual adhesion, multifunctional composites, patterning, and everyday plastic objects. We also achieved cell-free protein production that had not been possible by petrochemical-based products. We expect our biomass DNA conversion approach to be adaptable to other biomass molecules including biomass proteins. We envision a promising and exciting era coming where biomass may replace petrochemicals for most if not all petro-based products.

将生物质 DNA 转化为可生物降解材料，从凝胶到塑料，以减少石化消耗

古代生物质是包括塑料在内的石化产品的主要来源，这些石化产品本质上难以降解，越来越多地污染地球生态系统，包括我们的海洋。通过用可降解和可再生材料替代甚至替代大部分石化产品来减少消耗，对于可持续发展的未来来说是不可避免和紧迫的。我们在此报告了一种独特的策略，可以大规模且低成本地将生物质 DNA 直接转化为多种材料，包括凝胶、膜和塑料，而无需首先将 DNA 分解成构建块，也无需聚合物合成。凭借出色且有时出乎意料的有用特性，我们将这些生物质 DNA 材料应用于药物输送、异常粘附、多功能复合材料、图案化和日常塑料物品的多种应用。我们还实现了石化产品无法实现的无细胞蛋白质生产。我们希望我们的生物质 DNA 转化方法适用于其他生物质分子，包括生物质蛋白质。我们设想一个充满希望和激动人心的时代即将到来，在这个时代，生物质可能会取代大多数（如果不是所有）基于石油的产品的石化产品。
