Nanoparticles can be designed with various functionalities to facilitate drug delivery:
Surface modification: By attaching specific ligands or antibodies to the surface of nanoparticles, they can recognize and bind to target cells. Controlled release: Nanoparticles can be engineered to release the drug at a controlled rate, ensuring a steady therapeutic effect. Stealth properties: Coating nanoparticles with biocompatible polymers like PEG (polyethylene glycol) can evade the immune system, prolonging their circulation time.
