Nanoparticles for drug delivery to the brain which leads to an overall larger issue of toxicity. In the early 21st century, extensive research is occurring in the field of nanoparticle drug delivery systems to the brain. One of the common diseases being studied in neuroscience today is Alzheimer's disease. Many studies have been done to show how nanoparticles can be used as a platform to deliver therapeutic drugs to these patients suffering from the disease.
