摘　　要：在生物体内部存在许多的液晶现象。通过对液晶光学性能、温度敏感性等研究,发现生物体中液晶态结构的物理化学性质的变化与生命过程紧密相关。生物液晶状态在自然界普遍存在。通过精细的研究生命体液晶态结构的变化规律可以更好的了解生物组织结构特征、信号传导等生物过程。利用液晶的特性及其与生物体组织间的作用机制联系,将其应用于生物检测、药物运输、构建新型仿生材料等。本文综述了液晶的发现和发展,生物液晶的内容以及液晶在生命科学领域中的应用。There are many liquid crystal phenomenon within organisms.We obtained that the changes of the chemical and physical properties of liquid crystal state are related to the process of life closely through studying the temperature sensitivity,optical properties and other properties of liquid crystal.Biological liquid crystal states are common in nature.Studying the structure change law of liquid crystal state in the life can make us understand the biological processes better,such as biological organization structure characteristics,signal transduction and so on.Using the characteristics of liquid crystal and the relationship of interaction mechanism between liquid crystal and biological tissue,liquid crystal has been applied in the bionic biological detection,drug transport,construct new material,etc.We have reviewed in this paper that the discovery and development of liquid crystal,the content of the biological liquid crystal and the applications of liquid crystal in the field of life science.
