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 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.
在这项研究中，从香蕉中提取并功能化了脱氧核糖核酸（DNA），并首次将其用作各向异性液晶（LC）的取向层。我们的研究旨在从香蕉中提取和研究 DNA - 合成和研究与各种表面活性剂的 DNA 复合物，以检验此类复合物作为电光换能器中的取向层的有用性。我们提出了一种从香蕉中用表面活性剂分离 DNA 的简单且环保的合成方法，因此我们将从香蕉中分离出的 DNA 转化为功能化的取向层。香蕉中分离出的与阳离子表面活性剂复合的生物聚合物取向层，如脱氧核糖核酸（DNA），是常用但有毒的聚酰亚胺取向层的极好替代品。基于 DNA 的材料因其出色的光学和物理性能、生物降解性和低成本生产而在光子学应用和生物传感器方面具有广阔的应用前景。该研究的新颖之处在于，这些材料有可能作为可生物降解的生物聚合物取向层用于光学器件，而不是通常对环境有害的传统聚合物。
