Nanomedicine focuses on the use of nanoparticles for the targeted transport of drugs to the central nervous system (CNS). Studies in rodents have shown that nanoparticles can bypass the blood-brain barrier by transporting drugs such as risperidone through the olfactory nerves directly into the CNS[1]. Intranasal vaccination with nanoparticles expressing pneumococcal surface antigens is another possibility[1]. The use of nano-carriers for targeted gene therapy through the foramen rotundum to the scala tympani is promising[1]. Liposomal and polymerosomal nanoparticles serve for the targeted transport of drugs when injected into the foramen rotundum[1]. Nanoparticles enable diagnosis, therapy, including chemotherapy and radiotherapy, with organ- or cell-specific delivery[2][3]. These systems reduce side effects and promote individualized treatment[3].
