Polymers are used to formulate polymeric micelles that provide physical and chemical stability of drugs that are encapsulated into them. Moreover, the drugs are encapsulated in the core portion (hydrophobic inner) of micelles and another portion is the shell portion (hydrophilic outer) which provides hydrophilicity to the hydrophobic drug. Delivery of hydrophobic drugs by micelles is easy and preferred due to the nano size structure, well association, low toxicity, biocompatible, well core structure, and a high stability. Several methods of preparation of micelles such as - thin film hydration, solvent evaporation, dialysis, and direct dissolution are discussed here. Micelles formulations in pharmaceutical industries are preferred because they enhance the solubility and bioavailability of drugs of BCS class II and IV. This review focuses on various strategies to overcome the problems related to poor aqueous solubility and bioavailability of drugs, micellar solubilization, and application of micelles for various drug delivery.

There are many neurodegenerative diseases such as Alzheimer’s disease, Parkinson’s disease, spinal muscular atrophy, Levy body disease, etc. Alzheimer’s disease and Parkinson’s disease are most commonly found. Neurodegenerative diseases occur due to the degradation of neurons in the brain and the spinal cord. The diagnosis of both diseases has increased, however, the successful treatment is still very limited because of the lower ability of the drug to cross the blood-brain barrier (BBB). It is a big challenge to deliver the drug to the brain, because only small and lipid-soluble agents cross the BBB, by considering this assumption, the liposomal drug delivery system is considered one of the effective treatments in neurodegenerative diseases. Liposomes are considered to be an ideal carrier as they are flexible, biocompatible, and can carry different types of therapeutic molecules across the BBB.

Ultrafine dispersions with varying drug loading, viscoelastic properties, and aesthetic characteristics may be useful for the administration of medication. A 20–500-nanometer droplet size range for nanoemulsions has been established. The biological behavior of a nanoemulsions formulation is heavily influenced by its droplet diameter and surface properties. Small droplet size results in clear emulsions; therefore, the appearance of the product is unaffected even by the addition of an oil phase. Nanoemulsions are oil-in-water dispersions that are transparent or translucent and are stabilized by an interfacial layer of surfactants and cosurfactant particles with droplet size smaller than 100 nm. New nanoscience-based technologies are becoming increasingly popular as a means of improving food safety, quality, and nutrition. In this field, nanoemulsions have been a key focus since they can be readily manufactured using current food components and technology. Food nanoemulsions, which are tiny oil droplets distributed in water, are being used as delivery methods for a variety of hydrophobic compounds, including nutrients, nutraceuticals, antioxidants, and antimicrobial agents.
