Liquid Crystals: Characteristics, Types of Phases and Applications in Drug Delivery

The present review article relates to some theoretical aspects of liquid crystals, particularly types and phases of liquid crystals. In recent years mesophase has gained a great deal of attention and is yet another exciting lipid-based system for drugs, Proteins, and vaccine delivery. On the whole, the existing research advancement of different phases of liquid crystals as a drug delivery system has been discussed and explored in detail. It is concluded that different phases of liquid crystals are promising to sustain the drug release from the internal nanostructure. Peptide-based therapeutics and enzymes can also be delivered through liquid crystals. Liquid crystals may be the drug carriers of choice soon.
