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.
Claims17
A liquid crystal composition, comprising:
- at least one cell culture medium component selected from a vitamin, an amino acid, a growth factor, or combinations of these, and
- at least two different liquid crystal compounds, wherein the first liquid crystal and the second liquid crystal both comprise at least one fluorine group, and at least one of the first liquid crystal and the second liquid crystal comprises a fluorinated phenyl group.
