Helical nanostructures are intriguing systems where geometry and chirality drive unique electronic phenomena, including the chiral-induced spin selectivity (CISS) effect. This interplay enables efficient spin polarization in electron transport, offering exciting prospects for spintronic applications. In this study, the electronic band structure of helical nanostructures is explored, highlighting how their geometry influences transport as well as spin-dependent properties. These insights will inspire further investigations into biological helices, such as peptides and proteins, which share similar structural motifs and could broaden our understanding of spin polarization in natural systems.
