Description
Liquid crystal (LC) biosensors are based on the mechanism of ordering transformations of LC molecules. Because of the anisotropic nature of LC molecules, LC has an extraordinary response to external stimuli and has highly responsive optical properties. The elastic force between LC molecules helps them for their orderly arrangement, which changes in response to a multitude of external stimuli such as temperature, adding biomolecules, and applying electric and magnetic fields. LC biosensors can be classified into LC-solid, LC-aqueous, and LC-droplet interface biosensors based on the LC-interaction surfaces. LC biosensors can detect target molecules such as nucleic acid, proteins, amino acids, and glucose. Aptamer-based LC biosensors have also been developed because of their high sensitivity. The advantage of LC in making a label-free biosensor lies in the fact that it requires minimal instrumentation, which heavily reduces the expense. There, it is one of the most promising types of biosensing techniques that are being developed. 2025 Scrivener Publishing LLC.
