Liquid Crystal Biosensors

Abstract:

The liquid crystal (LCD) biosensor is a new research area of sensor technology, which integrates the modern biotechnology and advanced electronic sensing technology. The feasibility and the principle of the LCD biosensor were mainly introduced in this paper. The chitosan films exhibited cholesteric phase LCD texture which can be seen by using the polarizing microscope (POM), and there is a main endothermic peak and exothermic peak of chitosan LCD solution in the DSC heating curve and cooling curve respectively. Chitosan maybe will be used as a sensing material by using its LCD characteristics. The development prospects are predicted.
