Liquid Crystals as Novel Drug Carrier: A Review
Abstract: Liquid crystal is a thermodynamic stable phase characterized by anisotropic properties, generally lying in the temperature range between the solid and isotropic liquid phase, hence are termed mesophase. Based on the way that liquid crystals are obtained, they can be classified into two types—thermotropic liquid crystals and lyotropic liquid crystals. The thermotropic liquid crystal is generated by variation of temperature in the liquid state, while the lyotropic liquid crystal is …
