Abstract

Liquid crystals (LCs) are used extensively by the electronics industry as display devices. Advances in the understanding of the liquid crystalline phase and the chemistry therein lead to the development of LC exhibiting faster switching speed with greater twist angle. This in turn lead to the emergence of liquid crystal displays, rendering dial-and-needle based displays (such as those used in various meters) and cathode ray tubes obsolete. In this article, we review the history of LC and their emergence as an invaluable material for display devices and the more recent discovery of their use as sensing elements in biosensors. This new application of LC as tools in the development of fast and simple biosensors is envisaged to gain more importance in the foreseeable future.
