    The electrical, electro-optical and dielectric properties of liquid crystals (LCs) are routinely manipulated in liquid-crystal display (LCD) devices, but their potential application in the development of biosensors is still in a nascent stage. In this review, utilising the electrical properties, electro-optical effect and dielectric anisotropy in LCs, we provide insights into several possible modes of label-free biodetection and describe how capacitance, electro-optical and dielectric measurements of various LCs assist in quantitative analysis of biomolecules. It is concluded that the electrically induced biosensing techniques proposed here provides new incentives for researchers to study the interaction between LCs and biomolecules and to resolve technical hurdles facing the development of LC-based biosensors.

    This paper is concerned with the dramatic purification effect of porous metal-organic frameworks (MOFs) and regeneration of a degraded liquid crystal (LC) as leftover from a flat-panel production line. By soaking MOFs in the LC, the correlation between the recovery of electrical properties and the water-sorption capacity of MOFs is unambiguously revealed. Experimental evidence from the data of voltage-dependent capacitance, dielectric spectroscopy and voltage holding ratio strongly suggests that the primary contaminant in a LC leftover is moisture. This investigation paves the way for feasible recycling of deteriorated LC materials. The approach reported in this study can be applied to many fluids for purification and regeneration.
