Thermotropic cubic mesophases

Webb12 jan. 2010 · The cubic phases are practically identified in aqueous solutions. The data on the structures in non-aqueous solutions are fragmentary [ 18 – 21 ]. Due to its structure, the cubic phase is inactive under polarized light. Therefore, small angle X-ray diffraction is the main source of information. 2.2. Identification of Liquid Crystalline Structures WebbA quantitative protein assay and label-free immunodetection based on dye-doped liquid crystal (DDLC) was developed in this study. The black dye incorporated as the dopant in the DDLC mixture features a high dichroic ratio and wide visible-light absorption band so that the level of disturbance in DDLC orientation in the presence of biomolecules can be …
