Abstract
Liquid crystal compositions that exhibit little or no toxicity with respect to cells include liquid crystals with chemical functional groups such as fluorine atoms, fluorophenyl groups, or difluorophenyl groups. Liquid crystals with little or no toxicity to cell lines may be added to cell culture media or added to components used in cell culture media. Cells may be grown in cell culture media that includes liquid crystals that exhibit little or no toxicity to cells.
