Liquid crystal （LC） biosensor is a new research area of sensor technology,which integrates the modern biotechnology and advanced electronic sensing technology. It is one kind of newly rising technology with the development of mutual infiltration and cross-link of biotechnology, materials technology, physics and electronic technology. The feasibility, principle, study and progress of the LC biosensor were mainly reviewed. The development foreground was prospected. And lyotropic liquid crystals have been employed to prepare biomimetic chitosan LC films. It may provided new ideas to people for further understanding and studying of LC biosensors, and promoted its development and application.
