Abstract 0507151Biology has remarkable solutions to engineering problems. In the context of fluid flows, organisms widely adopt the strategy of beating cilia for self-propulsion and to move fluids for particulate transport and feeding. For the engineering of integrated biochemical devices, solutions are needed for performing fluidic operations such as propulsion, mixing and separation. The investigators will pursue the creation and actuation of sheets of nanorods that serve as synthetic ciliated surfaces, and study their properties with a focus on fluid dynamics and applications in microfluidics. They will develop materials and processing to create controlled patterning of actuating cilia in sheets and within microfluidic systems. They will study the fluid dynamics generated by nanorods through a combination of sophisticated fluid modeling and nanoscale tracking of fluid motion. This project will develop both a new understanding of how biology moves fluids and how, in turn, we can engineer such structures for new compact analytical and medical technology applications. This program will create an educational microscopy and nanotechnology open lab that will allow middle and high school teachers remote access to the AFM to explore biological samples such as cilia and to explore magnetoelastomer compounds for engineered structures.

摘要0507151生物学对工程问题具有显著的解决方案。在流体流动的背景下，生物广泛采用拍打纤毛的策略进行自我推进，并移动流体进行颗粒运输和取食。对于集成生化装置的工程，需要溶液来执行流体操作，如推进、混合和分离。研究人员将致力于创造和驱动纳米棒片，作为合成纤毛表面，并研究其特性，重点是流体动力学和微流体中的应用。他们将开发材料和工艺，以在薄片和微流体系统中创建可控制的驱动纤毛图案。他们将通过结合复杂的流体建模和纳米级流体运动跟踪来研究纳米棒产生的流体动力学。这个项目将对生物如何移动流体，以及如何反过来，我们可以为新的紧凑的分析和医疗技术应用设计这样的结构产生新的理解。该项目将创建一个教育显微镜和纳米技术开放实验室，允许初中和高中教师远程访问AFM，以探索生物样本，如纤毛，并探索工程结构的磁弹性体化合物。
