Mitigating corrosion is a grand challenge that costs the United States nearly half a trillion dollars annually. Current corrosion control measures, which mainly rely on chemical coatings, often come with high cost and risks to human and environmental health. Microorganisms play key roles in corrosion, in which they can either accelerate or inhibit corrosion of metal surfaces. In this project, the researchers will develop a biological coating system fabricated with 3D bioprinting that can be applied for corrosion control. This bio-inspired coating design takes advantage of naturally occurring microorganisms that strongly inhibit corrosion. By harnessing the power of microorganisms and microbial biofilms, the biological coating developed through this project will provide long-lasting protection against corrosion to many types of infrastructure, improving their resilience and sustainability.To develop this biological anti-corrosion coating, the researchers hypothesize that both the chemistry and microbiology of the coating material need to be deliberately designed and fabricated using 3D bioprinting. This biotechnology development also requires co-production with a convergent team of interdisciplinary academic researchers and experts from industry and government, especially as it can be applied to many types of infrastructure and surfaces. To accomplish these goals, this Phase 1 project will (1) develop an initial design of the 3D printed biological coating, and (2) establish proof-of-concept that functional and self-healing microbial biofilms can be 3D bioprinted. Specific target industries and surfaces for the biological anti-corrosion coating system in Phase 1 include vehicle parts, agricultural machinery, and transportation and energy infrastructure. Both objectives will be carried out through an iterative and collaborative approach between the academic, industry, and government project partners.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

缓解腐蚀是一个巨大的挑战，每年耗资近半万亿美元。当前的腐蚀控制措施主要依赖化学涂料，通常会带来高成本和风险对人类和环境健康的风险。微生物在腐蚀中起关键作用，在腐蚀中可以加速或抑制金属表面的腐蚀。在这个项目中，研究人员将开发一种用3D生物打印制造的生物涂料系统，可用于腐蚀。这种以生物启发的涂料设计利用了强烈抑制腐蚀的天然微生物。通过利用微生物和微生物生物膜的力量，通过该项目开发的生物涂层将提供长期保护的保护，以防止对许多类型的基础设施，改善其弹性和可持续性。为了开发这种生物抗腐蚀性，研究人员使用涂料的化学和微生物来进行涂料和微生物的设计，以供涂料和微生物进行涂料。这种生物技术发展还需要与来自行业和政府的跨学科学术研究人员以及专家组成的融合团队共同生产，特别是因为它可以应用于许多类型的基础设施和表面。为了实现这些目标，该第1阶段项目将（1）开发3D打印生物涂层的初始设计，以及（2）确定概念证明，功能性和自我修复的微生物生物膜可以是3D生物打印。第1阶段生物抗腐蚀系统的特定目标行业和表面包括车辆零件，农业机械以及运输和能源基础设施。这两个目标都将通过学术，行业和政府项目合作伙伴之间的迭代和协作方法来实现。该奖项反映了NSF的法定使命，并被认为是值得通过基金会的知识分子优点和更广泛的影响来通过评估来支持的。
