1. Nanoparticles: These include liposomes, dendrimers, and polymeric nanoparticles, which can encapsulate drugs for targeted delivery. 2. Nanofibers: These structures can be used for controlled drug release in wound dressings and tissue engineering. 3. Nanoshells and Nanotubes: These can enhance the delivery of drugs to specific sites, such as tumors, through mechanisms like hyperthermia.
