Abstract

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.
