中文摘要：生物大分子可能发生自组装，并在培养基中表现出特定的集体行为。虽然已对组装程序进行研究以解开谜团，但很少在动态系统中的直接显示集体行为和相变过程。本文研究M13液滴的干燥过程，并用刮刀涂布法成功地进行了模拟。通过原子力显微镜测量沉积膜中的形态，并使用偏光光学显微镜实时捕获液晶相显影。接触线附近的集体行为表现为弯月面曲线的形状和颗粒运动速度。考虑到流变性质和流动性，合成的手性膜可用于排列金纳米棒，并且该方法提供了以M13噬菌体作为多功能手性结构支架的方案。
外文摘要：Biomacromolecules are likely to undergo self-assembly and show specific collective behavior concentrated in the medium. Although the assembly procedures have been studied for unraveling their mysteries, there are few cases to directly demonstrate the collective behavior and phase transition process in dynamic systems. In the contribution, the drying process of M13 droplet is investigated, and can be successfully simulated by a doctor blade coating method. The morphologies in the deposited film are measured by atomic force microscopy and the liquid crystal phase development is captured in real time using polarized optical microscope. Collective behaviors near the contact line are characterized by the shape of meniscus curve and particle movement velocity. With considering rheological properties and flow, the resultant chiral film is used to align gold nanorods, and this approach can suggest a way to use M13 bacteriophage as a scaffold for the multi-functional chiral structures.
