Silk protein-based hydrogel materials suitable for hosting living microalgae due to the biocompatibility and ambient conditions gelation were developed. The silk was selected due to its robust mechanical properties, safe and compatible utility, green sourcing, and versatile materials formation. Through a series of assessments the mechanics and gelation kinetics of the hydrogel materials were optimized for three-dimensional (3D) printing. Silk hydrogel structures containing a marine microalgal strain, Platymonas sp. were printed and these structures supported cell proliferation for at least 4 weeks and consistent photosynthetic activity for more than 90 days, the limits of the study time frame. This long-term cell viability and function suggest that these systems may be suitable for a broad range of applications, such as oxygen replenishment and carbon dioxide reduction toward a green, healthier indoor environment.

用于环境应用的功能性微藻丝结构的3D打印

由于生物相容性和环境条件凝胶化，开发了适合于容纳活微藻的基于丝蛋白的水凝胶材料。选择丝绸的原因是其坚固的机械性能，安全和兼容的实用性，绿色采购以及通用的材料成型方法。通过一系列评估，优化了水凝胶材料的力学和胶凝动力学，以进行三维（3D）打印。含有海洋微藻菌株，侧柏的丝水凝胶结构sp。印刷这些结构，这些结构支持细胞增殖至少4周，并保持超过90天的一致光合作用活性，这是研究时间范围的限制。这种长期的细胞活力和功能表明，这些系统可能适用于广泛的应用，例如向绿色，更健康的室内环境补充氧气和减少二氧化碳。
