There are several methods employed for controlled release in cancer therapy:
Polymeric Micelles: These are self-assembling amphiphilic block copolymers that can encapsulate hydrophobic drugs and release them in a controlled manner. Liposomes: These are spherical vesicles with a phospholipid bilayer that can encapsulate both hydrophilic and hydrophobic drugs, providing controlled release. Nanoparticles: These include a variety of materials such as polymers, metals, and lipids that can be engineered to release drugs at a controlled rate. Hydrogels: These are networks of polymer chains that can hold a large amount of water and release drugs in response to environmental triggers like pH or temperature. Drug-Eluting Stents: These are stents coated with anti-cancer drugs that are slowly released to the surrounding tissue.
