Nanomedicine has recently emerged as an exciting tool able to improve the early diagnosis and treatment of a
variety of intractable or age-related brain disorders. The most relevant properties of nanomaterials are that they can be engineered
to cross the blood brain barrier, to target specific cells and molecules and to act as vehicles for drugs. Potentially
beneficial properties of nanotherapeutics derived from its unique characteristics include improved efficacy, safety, sensitivity
and personalization compared to conventional medicines. In this review, recent advances in available nanostructures
and nanomaterials for brain applications will be described. Then, the latest applications of nanotechnology for the diagnosis
and treatment of neurological disorders, in particular brain tumors and neurodegenerative diseases, will be reviewed.
Recent investigations of the neurotoxicity of the nanomaterial both in vitro and in vivo will be summarized. Finally, the
ongoing challenges that have to be meet if new nanomedical products are to be put on the market will be discussed and
some future directions will be outlined.
