摘要

肽纳米管（PNTs）是一种生物电子管，具有压电性、热释电性、铁电性和双折射性。双折射是一种光学特性，可用于确定 PNT 的有序程度、取向、大小和形状。在这项研究中，我们使用了一种定制的光学仪器，在不同的电场和温度条件下定量测量 PNT 的三维双折射。这项工作还包括对准和定向 PNT 的技术，并讨论了双折射测量在 PNT 研究中的作用。

Quantitative 3-D Optical Birefringence in Peptide Bioelectrets

Peptide nanotubes (PNTs) are bioelectrets that exhibit piezoelectricity, pyroelectricity, ferroelectricity, and birefringence. Birefringence is an optical property that can be used to determine the degree of order, orientation, size, and shape of PNTs. In this work, a custom-built optical apparatus is used to quantitatively measure birefringence in three dimensions of PNTs under varying electric fields and temperature. This work also includes techniques for aligning and orienting PNTs and discusses the role of birefringence measurements in the study of PNTs.
