Drug Delivery Innovations for Enhancing the Anticancer Potential of Vitamin E Isoforms and Their Derivatives

Schematic structure of liposomes, micelles, nanocapsules, and nanospheres. Liposomes are composed of one or more lipid bilayer structures surrounding an aqueous core where the drug is encapsulated. Micelles contain a hydrophilic shell and a hydrophobic core for carrying lipophilic drugs. Nanocapsules encapsulate a drug in an inner space surrounded by a polymer membrane while nanospheres are solid polymers that incorporate a drug in their matrix through uniform dispersion.
