A liquid crystal biosensor for specific detection of antigens [PDF]

Sensing and Bio-Sensing Research, 2016
Following the principle of the enzyme-linked immunosorbent assay (ELISA) pathogen detection method, we demonstrate specific sensing of goat Immunoglobulin G (IgG) by a nematic liquid crystal material.

Unwinding of a cholesteric liquid crystal and bidirectional surface anchoring [PDF]

, 2013
We examine the influence of bidirectional anchoring on the unwinding of a planar cholesteric liquid crystal induced by the application of a magnetic field. We consider a liquid crystal layer confined between two plates with the helical axis perpendicular

Flexoelectric polarisation effects in nematic liquid crystal phase gratings [PDF]

, 2008
Nematic phase gratings have been studied in which a planar nematic layer of thickness 17.2 μm is sandwiched between two glass substrates coated with an alignment polymer.

Liquid crystal thermography in neuropathic assessment of the diabetic foot. [PDF]

Primary aetiologic factors of diabetic foot disease include peripheral neuropathy and peripheral vascular disease. Assessment of circulation, neuropathy, and foot pressure is employed routinely to determine the risk of foot ulceration in the patient ...

Publisher Correction: Electrically driven three-dimensional solitary waves as director bullets in nematic liquid crystals

Nature Communications, 2018
The original version of this article contained an error in the description of Supplementary Movie 7, which incorrectly read ‘Collision resulting in annihilation of two solitons. U  = 45.1 V, f  = 600 Hz, T = 50 °C, d = 8.0 μm. The original movie is taken

Dynamic Control of Speed and Trajectories of Active Droplets in a Nematic Environment by Electric Field and Focused Laser Beam

Frontiers in Physics, 2021
One objective of active matter science is to unveil principles by which chaotic microscale dynamics could be transformed into useful work. A nematic liquid crystal environment offers a number of possibilities, one of which is a directional motion of an ...

Living Liquid Crystals [PDF]

Biophysical Journal, 2014
Significance We propose a class of active matter, the living liquid crystal (LLC), representing motile rod-shaped bacteria placed in water-based nontoxic liquid crystal. Long-range orientational order of the liquid crystal and the swimming activity of bacteria demonstrate a strong coupling that dramatically alters individual and ...

Fine structure of the topological defect cores studied for disclinations in lyotropic chromonic liquid crystals

Nature Communications, 2017
Topological defects play important roles in determining material properties, whilst their core regions remain unexplored due to strongly distorted structures. Zhouet al.
