“…In addition, AsO 4 3− also has toxicity to human beings. Majeed et al [ 164 ] elucidated the photocatalytic effect of TiO 2 on the LC sensor for AsO 4 3− detection. Upon exposure to UV light, the TiO 2 in the sensor can generate electron–hole pairs, which can absorb AsO 4 3− to form coordination compounds, leading to the disturbance of the LCs.…”

Liquid crystals (LCs) are nanophotonic materials which can interact with light in the molecular scale. While the LCs are widely used in various displays, last decade has witnessed emerging applications of the LCs for nondisplays. Based on the unique stimuli–responsive property and optical property, the applications of the LCs in the field of sensors are widely explored. In addition, ions are widely distributed in nature and bionts, playing critical roles in many physiological activities and ecological cycles. Appropriate amount of ions is beneficial to the human body, while the excess ions can cause irreversible damages. As a result, a variety of LC sensors are proposed to detect the ion concentration in both body fluids and water samples. This article reviews the design principles, applications, and existing problems of the LC ion sensors. The geometries, alignments, and optical signals of the sensors, which can guide the design of the devices, are first discussed. Afterward, two types of LC ion sensors aiming at detecting metal ions and nonmetallic ions, respectively, are illustrated. Finally, the current challenges and potential development directions of the LC ion sensors are introduced briefly.

“…The adsorption of AsO 4 3À on the electron hole of TiO 2 [164] proposed by Chen et al [156] Such a film is achieved by the UV polymerization of the CLC monomers and the chiral H-bonded assembly. The reflection band showed an obvious redshift with the increase in the pH value.…”
