Novel and Classical Materials Used in the Plane of Polarization of Light Rotation: Liquid Crystal with WS₂ Nanotubes

Abstract

It is well known that among the materials used in the daily lives of individuals and also in industrial applications, the specific structures applied in biomedicine occupy a special place. It is connected with the possibility to expand our basic physical-chemical knowledge and regarded to the real application of novel structures in the interdisciplinary arena. In this paper, a comparative study is conducted on the influence of different materials: sugar, DNA, WS2 nanoparticles, dyes—on the rotation of the plane of polarization of light. Firstly, this effect is shown namely for a liquid crystal mixture doped with WS2 nanotubes. On the one hand, it is shown that the new materials are quite suitable for use in sugar-meters and polarimeter devices instead of sugar solutions. On the other hand, the rotation of the plane of polarization of light in solutions with DNA and WS2 nanoparticles in water or in the liquid crystal mixture can predict a larger angle of the rotation of the polarization plane of the light and can find a better design than in volumetric classical sugar solutions. This makes it possible to expand the application of these materials to the technical devices.
