| Abstract | Liquid crystals (LC) have been drastically protracted in recent years, due to the ferret out of novel nanophysiochemical properties at surfaces. Physiochemical characteristics, such as weak intermolecular forces manifested like odd-even effect, hydrogen bonding, and electric double layers make them ideal for variety of applications. Furthermore, the orientation of LC exploits the conventional and novel detection method for protein binding event on nanostructured surfaces and protein crystallization on lipid monolayers. These explorations include the detection of parts per billion (ppb) chemical warfare agents on surfaces as well as new mechanisms for driving the reorientation of liquid crystals. The scope of the present review attempts the recent progress on using LC to amplify a wide range of engineered surface chemistry progressed from liquid-solid and liquid-aqueous interfaces. The distinct features of LC role in imaging and biosensing have been discussed. From these studies, it is clear that the LC has the enormous potential as a promising material for the biomedical applications. |
