| contents | In this study, deoxyribonucleic acid (DNA) from bananas was extracted and functionalized and used for the first time as a homeotropic alignment layer for liquid crystals (LCs). Our research was aimed at extracting and investigating DNA from bananas via the synthesis and study of DNA complexes with various surfactants to examine the usefulness of such a complex as an alignment layer in electro-optical transducers. We proposed a simple and eco-friendly synthesis of the DNA complexes isolated from bananas with surfactants, so we transformed the DNA isolated from bananas into a functionalized alignment layer. A biopolymer alignment layer like deoxyribonucleic acid (DNA) from a banana complexed with a cationic surfactant is an excellent alternative to a commonly used but toxic polyimide alignment layer. DNA-based materials are promising for photonic applications and biosensors because of their excellent optical and physical properties, biodegradability, and low production cost. The novelty of the research lies in the potential use of these materials as biodegradable biopolymer alignment layers for optical devices instead of conventional polymers, which are usually harmful for the environment. |
