To overcome these challenges, advanced delivery systems have been developed:
- Nanoparticles: Tiny particles that can deliver drugs directly to cancer cells, improving selectivity and reducing side effects. - Liposomes: Spherical vesicles that encapsulate the drug, enhancing delivery to the tumor site and protecting healthy tissues. - Antibody-Drug Conjugates (ADCs): Combine an antibody specific to cancer cells with a cytotoxic drug, allowing for targeted delivery. - Polymeric Micelles: Amphiphilic molecules that form micelles in aqueous solutions, enhancing the solubility and stability of hydrophobic drugs. - Hydrogels: Networks of polymer chains that can hold large amounts of water and release drugs in a controlled manner.
